View 3 RepliesI have a 2000 f150 knocking cant figure out what it is I thought maybe it was rod knocking so I pulled the plug wires and it continues to knock sounds like its coming from the bottom of the motor could this be crank shaft problems ?
View 3 RepliesI am a proud new owner of a 2000 X 6.8l 2wd with the 4.3 rear end .
I have had the truck for 2 weeks now . When I bought her , she ran a little rough but I expected as much after sitting for 6 months ... After driving her home I began to start a massive tune up , because she was acting like there was a miss ... The miss only started after she was at normal operating temp and at first only when at cruising speeds in overdrive on the freeway , it progressively got worse ... The miss became all the time once up to normal operating temp but will do it wether she is in any gear or even park .... Oh and the miss is NEVER at the same time it is always completely random ...
I have changed all 10 coils , all 10 plugs , the PVC valve , and I am changing the fuel filter this afternoon ... Other then that I think I can hear a vacuum leak , but I have tried spraying carburetor cleaner around the engine bay as instructed by a " ford expert " at the local auto parts store and I did not notice any change ... After I install the new fuel filter I am going to fill her full of 93 octane and add a bottle or 2 for Lucas octane boost as well as the Lucas injector cleaner ...
Other then these things I am at a complete loss ! This is my first v10 ford so I am a little at a loss ... Now if this was my wife's BMW 760 or my Lexus IS 300 I would not be having this problem.
Just hoping that there is something common that causes this problem. This thing can idle just as smooth as you could want one to and the next time it will have a dead miss, and the miss is not consistent. It may miss like three hits then be ok a little then miss a little. There is no CE light or codes. Again just hoping there is something common.
View 2 RepliesMy 86 f150 will start great and run when cold, but when it warns up it won't start. I will turn over strong, but it just won't fire. I have replaced the ecm and the Icm. What else could it be?
View 6 Replies02. Cold a/c works but as motor warms up, compressor kicks off and light on button blinks. This started several years ago and simple reset button, worked as should. Now once it flashes it wont reset until everything is cooled down. . put gauges on and seemed normal sometime back. Its like there is a faulty thermostat that may be issue.

View 7 RepliesMy feed truck (2001 ext cab 4x4 7.3 198k) had a cold starting issue I fixed with new gp relay. Now I noticed when it gets down below 30 degrees it has a cylinder miss until motor warms up. I don't doubt injectors are in my future. I was wondering though if that is common for worn injectors or if maybe something else has gone haywire and how long can I run it like that before something else tears up? after about 7-10 min the miss goes away and I don't notice it. I would like to get through the winter before messing with it or having injectors put in it...
View 14 RepliesI just bought a 99 Ranger 3.0 L. Truck runs great while cold. After it warms up however it has a misfire. I knew that when I bought it, and bought it cheap enough that I figured even if its down on compression or something serious, I could afford to throw a long block in it. It also is throwing a check engine light. I have not read the codes yet, waiting on a scanner I purchased. Ive got new plugs and wires for it, not yet installed. Also, have not checked compression yet. Been too busy to work on it much so far. Just curious if there is anything I can look at before the new scanner arrives.
View 8 RepliesI bought a 2003 Ford Ranger, 2.3, 5 speed manual. It is hard to shift after it warms up. I test drove it when it was below freezing, so I didn't notice it at first. The warmer the day and quicker the truck warms up, the worse it is. It goes into gear with no problem when the engine is off or if I'm still moving, but if I'm stopped there are times it is hard to get into gear. This really sounded like a clutch that wasn't fully disengaging to me, so I decided to pull it apart. I didn't check the movement at the slave before I started, but I did find the master was a little wet at the rod in the cab.
So, I did the following:
- New clutch master cylinder (system bled out of truck to eliminate air)
- New slave cylinder and bearing
- New pilot bearing
- Changed transmission fluid - Mercon III ATF
I inspected the clutch/pressure plate and it was in good shape and looked like it might have had 10K - 20K miles on it. The last owner said it was recently replaced and it looked it. So, I put it back in. After I was done, I checked the movement at the slave/pressure plate and it is moving about 3/8" - 1/2" when the pedal is down. I was happy and thought this would solve the problem since the old pilot bearing seemed stiff and I saw the leak on the back of the master cylinder.
I drove it and all felt fine at first, but it was a cool day and I didn't drive it that long. When it was warmer over the next couple of days, it started getting hard to shift again. It's not been quite as bad as before, but still doesn't shift right.
My 99 ranger has a strange issue its got a miss when the A/C is on, when going down the road I can feel the engine sorta pulse for a second, gets better the more I drive it, its got all new plugs and wires, not sure where else to look?
View 1 RepliesI have a 94 Ranger 4x4 with a 4.0 liter engine. The check engine light is on when cold and then after warms up, has trouble starting, seems to flood. When it does crank, rpms go wildly high to over 2,000. I feel it is the Mass Air Sensor but not sure as my mechanic does not have the equipment to read the codes.
View 1 RepliesI have a 98 4x4 with 145k miles and 4.0 OHV. Symptoms are as follows;
Uses ALOT of oil. 1 quart per 230 miles. Burning bad in rear cylinders, some in middle cylinders, none in front cylinders. Screams intake or PCV issues to me, not rings or valves. Never any smoke, not even on startup. No significant leaks. MPG always 18-20mpg.
Slightly rough idle.
Miss under load below 2k rpm. Not a terrible miss, but you can feel it. Has never lit the CEL. I know the CEL is good.
Never loses coolant. No coolant in oil or vice versa. Haven't done compression test, but doesn't seem like they ever tell you much anyway.
This weekend I replaced all intake gaskets, plug wires, cleaned oil residue off and regapped plugs (they are 3 months old), injector orings, and PCV valve. Flushed and burped radiator.
It's too soon to tell on the oil consumption, but I thought the intake gaskets would have cured the rough idle and misfire. The idle IS much better, but still not perfect. But the low rpm load miss is actually worse now. Still no CEL. Could it be storing codes without lighting the CEL? Also, how do you clear codes on these, can you just disconnect battery, or do you have to clear them with a scanner?
1993 ranger, 3.0 V6 203,000 miles. As engine warms up coolant in blown into over flow and spills out. At that point system is low and truck runs hotter than norman, 3/4 way across gage. What would be causing overflow to overfill from engine. Could it be a bad rad. cap? Just replaced head gaskets at 200,000 miles. Truck runs good. No oil in water, no sign of visible leakes other than overflow tank overfilling and loosing coolant.
View 10 Replies2002 Ranger XLT 4WD 4.0.. I was passing another car at about 55 when they also started speeding up (go figure) so I floored it and got on around them but before I lifted I felt it miss, the CEL began flashing so I slowed to the speed limit and went on to work. The light flashed for about a mile then went out. So on the way home I floored it again close to home and the CEL came on again. Got home and put the code reader on it and all it had was a random misfire so I have cleared it. The truck has new plugs, wires, etc for a complete tune-up. I don't usually run at full throttle so don't know if that would be normal for the Ranger, the Ranger was my wife's truck for 12 years and now is my DD. Need to clear this up? Thought of changing the fuel filter in that is still the original one.
View 8 RepliesI bought this from my brother in better than mint condition. Always maintained. Its generating a cyl #2 misfire code.
It starts and runs like new when cold, but when it warms up, it idles rough, and generates the code. after 1500 rpm it smooths right out and runs fine.
He had it to the dealer just before I bought it and they told him needed a new engine.
I am thinking bad injector, since what seems to be happening is, when cold it gets more fuel, or when u rev it gets more fuel, but at an idle and warm, it doesn't seem to be getting enough maybe. And I see from the maintenance records, a couple of other injectors have been replaced as well.
I think the dealer got tired of replacing injectors under warranty and tried to milk him for a new engine.

Quick back story I bought a 1999 Ford Ranger It is a 4 cyl with an auto trans the guy said it had some trouble with the tranny (major understatement) he also forgot to mention he cut out the CAT. so running a 4 banger off the header.
When you start the truck it rough idles but you have to hold the gas down til it warms up. You can shift into reverse but it labors the motor and the motor will not up the rpms kinda stays at idle and wants to die no matter how hard you accelerate and you can't move up a slight incline.
When you shift into drive you have to rev the motor to 3 grand an it will catch then move slowly forward. no matter how high the revs go. The fluid levels are a tad above the full level and a bit dark for my liking.
Ok, I used an OBDII scan tool from the parts store and it came up with 3 codes P0351, P0352, P0500. From my internet search the first two seem to be coil related which explains why the motor is running like garbage. The last may or may not have to do with what the tranny is doing.
I have a 1987 ranger 2.9 V6. Have a intermittent miss @ idle when warmed up. What is the proper way to pull the codes from the computer, i,st something about counting flashes or lights...
View 6 Replies1993 3.0 V6 5 Spd ... Changed plugs wires Cap and rotor put in a new idle control Valve. No Check engine light. When i am running down the road feels like it surges,hickups, while its at idle the motor shakes like no tomorrow. Just dont want to throw money at something and not be the part that was wrong. Truck has plenty of pickup runs like a raped ape going down the highway. seems when i accelerate the miss clears up and not there. RPM gauge needle has some movement in it. Also put in K&N filter fuel filter as well.
