Ford Ranger / B-Series :: 2000 - Check Engine Light / Misfire On Cylinder 5
Sep 22, 2012
OK, got a check engine light today when I fired up the Ranger. Like I posted previously it is running kind of rough so guess I know why now.
Took it down and got the codes read it have a miss fire on cylinder 5. Picked up some plugs and wires, got to get those E3's out of there, but kind of think that's really not going to fix the problem. So that probably leaves the coil pack or injectors.
So what's the consensus on the best coils to use? Also, being an 18 wheeler for more years than I care to remember, I've learned swapping just 1 injector is never the way to go. So whats the best type of injectors to get and where the best place to get them should it come to that?
Oh, it's a 2000 3.0L Flex fuel 5 speed.

I have a 2003 ranger and have had ongoing problems with misfire cylinder six and have had three different mechanics diagnose the problem as a bad ground. I have replaced all plugs, wires, coil pack, injectors and am constantly pulling the plug on cylinder six, cleaning and often replacing, I also disconnect the battery so it resets the check engine light and it runs fine for about 100 miles and starts running rough again and on goes the check engine light. I have 134000 miles and have maintained it since new.....

Got a 1996 Ford Ranger with the 4.0L in it that has a misfire on the #3 cylinder and giving check engine code: P303. Have tried new plugs, wires, distributor, switching out the coil pack with a known good, checked injectors for pulse, checked injectors, moved injectors and still the misfire remains on #3. Removed the valve covers and all appears to be well.

1997 Ford Ranger with 190K miles has check engine light on with P302 computer code, meaning misfire on cylinder 2. Engine runs rough at idle only once it warms up, which only takes a minute. It is usually fine while driving, but it's a lot easier to feel a misfire at lower RPMs than at higher ones. Added fuel injector cleaner to gas for a couple tanks, no change. My mechanic has checked spark plugs, fuel injector, o2 sensor, and everything is ok. Dry compression test shows good compression. He thinks it may be a valve sticking, which means a valve job: expensive. Is there anything else that can be done? Why is there no misfire when it is first started?

This has been an issue for about 8 months now. I'm getting a misfire on cylinder 4. So far compression test, new gas filter, fuel injectors cleaned, spark plugs and wires replaced. coil pack replaced. Heater valve was leaking but was replaced.

My parents 2000 Ranger has an CEL for cylinder 4 misfire, but it will clear on its own and then start up days/weeks later, is this common? Could it be an injector?

I have a misfire mystery going on in my girlfriends 00 ranger. What is going on, is there is an intermittent misfire on #4. I have an ultra gauge hooked to it, so most of the time when it does it, it will flash a pending code. A lot of the time, the pending code will go away, but sometimes it will set the PO304 code.
First I tried a tune up. New plugs and wires, air cleaner, cleaned out the throttle body. This cured it, for a short while. Then we were back to the pending code / setting code for #4.
When I pull the plug on #4 it is sometimes wet with gas. If you put a new plug in it runs fine for a while. In fact the last time we took a several 100 mile trip with it right after plug change, and it ran great. The pulled plugs re always in good condition with no burn, oil, chips or glazing. I have been using the standard autolites that are in advance auto's computer for that engine. No issues with the other 5 so I figure they re good enough.
The day after we came back I get the call... Honey its doing it again. Often to the point of having no power at all.
But it will clear itself usually, if not a new plug for #4 will cure it immediately.
So I thought something is killing this plug.... Or flooding it. SO I ran 2 cans of sea foam though it, put in a new plug and an new wire. It fixed it for a week then it did it again.
Ok I think... maybe the coil pack is bad either killing the plug or just not firing it at all? So since the pack has never been change in its nearly 300K life (to my knowledge, shes had the truck since about 60K) What the heck.... a new coil pack for the old thing.
I have not had the chance to clean the MAF but we are talking misfire on one cylinder, every now and then with no real conditions that set it off. More often than not its a pending code that you can even hear or feel and other times its a full blown miss that drags the truck down. Well for a short while until it clears up or I replace the plug.
3 cans of seafoam surely would have cleared a sticky injector. I realize it could be a bad wire to that injector but I have not had the time to tear the fiddle bits off to get to it to clean and test it... or just replace it.
Honestly Ive had a lot of cars and trucks, I don't remember ever having to replace an injector. Ive had bad wires to them but they misbehave ALL the time. This problem is so intermittent its freaky.
She says it does it mostly when its cold or not totally warmed up. Almost always, by the time the engine is hot it goes away.
And hot for this truck is over 185F, which I think its too cold to be running and the thermostat needs changed BUT she thinks cool=good. I keep telling her no, cool is often not good, the engine needs to be up to the operating temp.... which to me means 190-200. Her ranger runs between 170-180 all the time. I doubt thats causing the problem but still.... I think new thermo is in order.
My thinking is since it runs so cool all the time, the issue might be related to a spike in the temp over 180 ish, that gods forbid is opening a crack somewhere to suck air or lose compression.
And a compression test is my next step on #4 if/when it does it again. Now I have had cracked valves before, I don't recall them acting this way. After all sometimes the thing will go 100s of miles under different driving conditions and run fine. I don't think a cracked valve would be that nice.
Shes getting @18 MPG mixed driving, when it runs t runs like a bear. It always fires right up. There is no smoke, white or black. There is no water in the oil, no oil in the water. No audible exhaust leaks. No ticks knocks or oddball noises. For its age and miles almost 300K it runs perfectly.
Well until it has its intermittent issue with the misfire, that isnt bad enough to actually set the code.

I have a ford Ranger with a 2.5 and 231,000 miles. I bought this truck with a misfire on #1 cylinder. drove it home and started it a couple days later and still misfire on #1 but as soon as you rev up the motor the #2 starts misfiring as well and dies. start it back up and misfire on #1, rev up the throttle and misfire on #2 also.
Here's what i have done so far. intake gaskets, plugs and wires, checked fuel pressure (good), swapped injectors on 1 and 2 with different injectors, timing belt, tensioner, swapped coils from primary to secondary no change, checked compression and all 155 and above.
I have talked to everyone i know and am getting no where. the truck can sit and run for a hour with a minor misfire on #1 but as soon as you hit the gas it starts another misfire on #2. I am thinking it is a ecm issue.

2000 4.2....Last year I had to replace the coil pack when it started running rough and had a code for a misfire on cylinder 3. It is doing the exact same thing now, same code, same cylinder. Is there something wrong that is causing this?

2000 Tacoma v6 has has always ran good, but has check engine light code P300 & P306. cly 3 & cly 6 missfire, lean bank 1. Vacuum test showed no problems.
I've changed plugs & wires, switched coils around cleaned mass air flow sensor, checked timing. Ran Seafoam through intake, and gas tank. Check engine light went out for about three miles, then came back on. What else can I do to keep that blinking check engine light off?

My 2000 ranger with the 3.0 is only getting around 10 or 11 mpg. It's got a check engine light on but the scanner just says lean condition. The truck also has a rough idle. I've replaced the fuel pressure regulator and fuel filter.

2000 Ranger 2wd 3.0 ... I bought my truck last summer for $1k from my neighbor, it has hit a deer so the grill is busted,front drivers fender bent up and bumper is bent all to heck. The old girl is rock solid reliable though and gets decent mileage with cruise heat and ac so I'm happy.
Anyways on to the point, I am having two big issues with it, the check engine light randomly comes on and causes it lose power sometimes at others you don't notice it. I have not been able to get codes read because it goes off every single time I go to someplace with a scanner. The light will usually go off if you floor it for a long stretch maf maybe?
The other issue is the transmission, I don't know for sure which tranny it is but the overdrive button does not work at all even though the fuses are good and when I drive down the highway second gear you have to let off for it to shift sometimes ( I've been leaning towards the valve body gasket for that) and lately it has started a horrible vibration kicking out of overdrive or just downshifting on hills etc.?
I forgot to mention it has 255k miles on it and I don't know the history besides the balljoint I replaced this week and radiator when I bought it.

So when I bought the car, it had a check engine light. I had it checked it said cylinder 5 misfire. I assumed it was the glow plug so I bought it and replaced the glow plugs myself. Check engine light went away for about a day then came back on. Got it checked again and still said cylinder 5 misfire. This is my first diesel and I'm clueless as to what's wrong.

I have a 2005 f150 with 96,000 miles. Long story short, last August I was headed to the mountains going up a steep long hill and the engine light come on. once i was over the pass the light went off. During my 4 wheelin' trip it never came back on until I was headed home and going over another pass and then it stayed on for a couple of days. I had it checked and it was a cylinder 5 misfire. I did some research and found that replacing the coil cover might fix the problem and if not the spark plugs would need to be changed.
I changed the coil cover, problems solved... until I headed to the mountains. light came on and then eventually went off later that day. I didnt think much of it. then a few months later i was headed to the mountains again and the light came on in the same place on the steep incline hill. I. took it back to the shop, same reading. I decided it was time to replace the spark plugs anyways so I would invest. I have new plugs and everything is good however, I had no plans to go to the mountains in the near future. Now, a few months later I headed to the mountains and crossed my fingers it would not come on but it did.
I've done the research again and it seemed like the coil cover and spark plugs are usually the cause of the problem...however I have changed mine. The light is now off again. I don't understand what is triggering the problem and what is really happening and if it is safe to keep taking to the mountains with this happening. I did notice that everything was fine at 60MPH but once i hit the hill and steeped on the gas to go 65 and hit 4-5RMP that is when the check engine light came on...

2001 Ford Ranger 4.0L V6... Okay so I bought my truck last September with 100K on it. Ran perfectly fine. No problems for for the first two months and then it started to misfire when at idle. Check Engine Light came on. Scanned and got a random multiple misfire code. I then changed the plugs and wires. Had to repair the threads for cylinder two. Did all that and it kind of but not really solved the problem. A few weeks later got another check engine light. Cylinder 3 misfire. Changed ignition coil. No better. Shortly thereafter I checked again whilst at work and read misfire on 3 and now 2. Currently replacing the intake manifold o-rings and cleaning out intake.

1997 Ford F150 - 133K Miles - 6cyl - 4.2L. This is a truck that gets less than 2K/year put on it. Has had "issues" with worn bearings and holding oil pressure for a few years now. Yesterday, the check engine light started flashing (as opposed to solidly lit) and the code came back as a cylinder #4 misfire (only the one code). The truck was clearly not firing on all cylinders and at idle, ran terribly (couldn't be driven). I just did a compression test on all the cylinders and all measured around 140-145psi except the #4 which read almost 170psi. I rechecked this a few times as well as a couple of the others and am now sure of the results. What could cause this one cylinder to have a higher compression ? Is whatever is causing this increase in the compression, also be the cause of them misfire ?? I'm stumped here and quite frankly, expected the compression on the #4 cylinder to be really low as opposed to the others.

Any way to check what's wrong myself?
Also just to double check, the cylinder number is 1, 3, 5, 7 for the passenger side front to back right? And 2, 4, 6, 8 for drivers side? And front to back means when looking at the front of the car? 2001 7.3 Excursion Limited with 232k miles...

I have a 2008 FX2 5.4L F150. Recently it began to lose power on a friend driving it out of town. He got a check engine light then it just progressively became unable to produce power. It ran but he got down to 10 mph before he could get to a firestone. I got it to a local Ford dealer and they say i need a new engine. They gave me codes for cam sensor and timing and #5 and #6 misfire. (344, 345)
No oil in radiator, no water in oil. The crazy thing is it runs like the day i bought it in Park. But once in gear it begins to cough and then eventually shudders and dies. I haven't changed plugs ever. I know... At about 75 miles it began to idle rough at times and in reverse. But once I revved up it went away.
I replaced both cam sensors but no luck. Today i put it on a tow truck to get a second opinion from a local engine shop. I actually backed it down my driveway, and pulled up to the tow truck with no issues. weird...

I figured something out on my ranger that has been bugging me for a while it was a third cly misfire so I changed the plugs and it went away for a while.the po told me he had just changed the plug wires so i didn't mess with those and it was an intermittent misfire so i changed the brain box because it was 15.00 at pull and save and it had been all updated boy did it run smooth for a while then the misfire came back. So I decided to check the 3rd cylinder plug wires and found out the one that is hard to change on the drivers side was badly rusted so i borrowed one off my windstar it was a little longer but boy does it run smoother and it doesn't die all the time and chug chug all the time now i just need to change the battery. i have already changed the clutch and the tranny twice i took one out of an 88 and it fit just fine by the way the engine is a 2.3 8 plug engine with over 230,000miles on it my next project is a timing belt and a heater core won't that be fun and yes i smell the antifreeze inside and don't like the stop leak like the last person put in.

Been awhile since I've been able to post but I've got a serious issue with my 2006 Ranger XLT 4L V6. So last night about 2 miles from home my check engine light started flashing like it was a at a rave and my engine wasn't acting right, also had the STRONG odor of raw gas, no other lights from the dash, no fluids leaking, oil was good n nothing in radiator but coolant. Was able to baby it to my current home but all my tools are in storage so had to wait to get my ODB scanner to see what's up. Scan came back as 'cylinder #3 misfire' & 'O2 sensor reading rich'.
Go cylinder #3 spark plug out and it were fouled bad. Got ride to the store and got a whole new set. Got back n got'em changed and fired ut up, idle still rough and check engine started flashing again and white cloud coming from exhaust pipe and STRONG odor of gas. Check and now have 'multiple missfire', 'cylinder #2 misfire' and 'cylinder #3 misfire'.
Shut it down go and double check ALL spark plug wires are connected and TRY to start, get about a turn n a half then starter spin. Try again and the engine won't even turn over. "Great I've seized the engine!" Was able to put a socket on the crankshaft pully and manually turn the engine over "whew didn't seize the engine", did this a couple of times and tried to start, was rough but eventually it fired up, still idling rough and again check engine light flashing, while it was running I pulled one plug wire at a time from the coilpack to see/feel the lighting and there was spark for the 3 I pulled, didn't affect engine idle.
Run codes and 'cylinder #3 misfire', so now that the engine is was warmed up I pulled out my ohm meter and started checking wire resistance. Cylinders #1, #2 were at .012, #3 was .011 and #5 was .009.
I've figured that the raw gas is due to cylinder #3 not burning and just pushing gas into the exhaust. So to the brass tacks, do I invest in a new set of wires? Or could it be the injector being stuck open and just flooding the cylinder? No when I originally pulled the #3 plug fuel did not spill out. Haven't pulled #3 again due to it being May in Arizona and had to take a break. I'm going on the assumption that the engine wouldn't start after a short run do to "hydraulic lock in cylinder #3", my manually turning the engine over cleared this and allowed the engine to start.
