Explorer :: 2000 Ford Misfiring / Running Rough / Sluggish Power
Feb 2, 2013
I have a 2000 ford explorer. 4x4 v6. One day i started it up and it was running rough. It had real sluggish power. Then the check engine light came on. I hooked it up to the code machine. The only readout was number 3 misfired. I replaced the plug and all was fine. A few months it happend again. I replaced it again and it was fine. Well it just happened again. I replaced it again. It ran good to work but on the way back no good. Light came on again. Hooked up the machine it read number 4 misfired and number 2 bank lean. So I replaced number 4. It still runs like shit rough idle and no power. Give it gas it dogs out but then it'll kick in if i get on it. Thinking it maybe a vaccum leak or intake leak or o-rings.

Lately I have been having problems loosing power. Truck wants to miss mostly going up hill and runs sluggish I'll pull off the road and let it idle for a minute and it will run fine. And it is only occasionally some days it don't happen at all and other days it happens quit often. New fuel filter, oil is good, had it on the scanner and isn't throwing any codes. Around 230k miles newer injectors.

My '99 Olds Intrigue was running rough & short on power. Autozone read a trouble code "random misfiring" (PM3000 I think it was). As suggested, I changed the plugs/wires and checked resistance on all three coils with no luck. Here's the real spooky thing: while driving down the street a couple days ago, the pipe between the catalytic converter & muffler separated, scaring me and sending all the children getting off the school bus scrambling for cover. There was no noise or odor prior to the 'drop out' - is there any chance that the one problems (a catalytic malfunction, or small leak in the area for instance) could be related to the misfiring? A mechanic - before the pipe plummeted - had suggested it might be an injector problem or the intake manifold but I figured that an injector problem would trigger a code.

My ranger just started running very rough. Like misfiring, but I think it may be the fuel pump. It starts and drives...but it surges then drives normal, as if fuel is being fed, then starved, then force fed etc. My father asked if I had trouble starting it and to be honest in the last 6 months it was a little harder to start on several occasions. On a few occasions it required more cranking. But that was only a few times.
I tried putting in a fuel injector cleaner and 93 octane gas but it is still running even rougher now. I changed out the fuel filter under the rail about a year ago (maybe 8000 miles ago at most). My father thinks the fuel pump is shot and he laughed because his went on his expedition and he said it is inside the fuel tank and there is no way to get at it without dropping the tank. Is that true? 2002 ranger xl 4cyl

My 99 Explorer XLT V6 SOHC has been misfiring lately. In idle the RPM needle fluctuates a bit and the vehicle vibrates and shakes. At night when the lights are on I notice them dim a bit as the engine struggles in idle. It doesn't stall very often at all. Accelerating I notice way less power and the engine studders. That's when the engine light comes on flashing. Then remains on solid afterward. I brought it to a mechanic friend who read the code and it was cylinder two misfire as well as the O2 censor.
I replaced the plugs and leads and censor. Noticed the plug in cylinder two had little to no gaping. Thought I had fixed the problem. The vehicle ran perfectly. Three or four days later driving on the hwy same problem came back. Thinking it must be the coil pack I got one for a good price and replaced it. Again, the truck ran great for four days and now the problem has returned. Same thing, shaking studdering and flashing engine light. I have verified the locations of the wires and plugs a few times so i believe they are all properly installed.

My neice bought a 2000 Explorer Sport back in November. Soon afterwards it developed a misfire and the CEL came on. I put on a new set of wires and a new set of plugs. I noticed when I replaced the plugs that the #3 plug was missing the ceramic near the electrode. I figured it was just a cheap Bosch plug and didn't give it much thought. The vehicle ran great.
Recently the misfire came back and the CEL came back on. When I pulled the plugs #3 had a cracked ceramic around the electrode, #4 was wet with fuel and not firing at all, and #6 was completely missing the ceramic around the electrode.
I replaced the plugs again, replaced the coil pack and cleaned the MAF sensor and it's running great again.
My question is, what would cause the ceramic to disintegrate on the plugs? There didn't seem to be any pinging or detonation. I replaced the coil pack because I thought maybe it was erratic, loading up on fuel and then causing a big bang and then destroying the plug. Are my thoughts way off? I want to make sure this is fixed so that it doesn't tear up anything else.

My 05 was running rough and misfiring quite frequently. After much deliberation, I took it in for a diagnostic hookup. The dealer said my driver side cat was clogged. Lucky for me, I was just under the warranty period(79673 miles). I have had it replaced and I can feel a noticeable difference in the way it runs. Could a clogged cat have made it run that poorly or am is it just in my head that it is running alot better?

So Friday before last my ex laid down on me while i was headed to work. So I parked it in a walmart parking lot and caught a ride to work with a friend then had it towed home that evening. Problem i was having is it started running really bad, miss firing, smoking, and sounding real rough, but I wasn't getting any trouble codes. So after both uvch's, icp, ipr, icp pigtail, checking fuel for water contamination and pulling my hair out, i decided to check the oil and found it to be 4 quarts low. Talk about feel like a knuckle head.... While it was down it did receive a new water pump, a diesel site 203* thermostat, new billet thermostat housing, Gooch's Radiator Flush Procedure, and some fresh rotella etc.

I just bought a 2000 ford explorer which didn't start... I put a new fuel filter, spark plugs and air filter in it...still not starting ...gonna do a a compression test tomm. and see if it the timing chains or tensioners... Sounds like its misfiring actually, it doesn't start with starting fluid sprayed in it....where is the ignition pickup located on these things? I still need to put a new ignition coil and wires on it. plugs were in horrendous shape and i thought that was the problem.

My 1999 lexus rx300 first threw a P1135 following a P0125, I tested the sensor and it was open at the heater circuit then then I was waiting the new part in the mail and during that time it kept running rough and then it threw a P0300, P0301, P0305, P0303. I was thinking that the PCM cannot monitor A/F ratio without the sensor so maybe the injector base pulse width was good enough. The misfire is are on bank 1, same as the bank 1 A/F sensor.

I bought my 2012 Camry, with 12,000 miles from the Dealership in December of 2013. The car was sold as CPO, car was purchased on Dec 30... just 6 weeks ago and I have had numerous issues with the car Misfiring. When I arrived at the dealer, the CHECK ENGINE and TIRE TRACTION lights are one and the car is running very rough as acknowledged by the service techs. For the 2nd time now, I am told they are not able to recreate the problem, so they are not able to fix it.
This is my 4th Toyota and I have NEVER had this many problems with a Toyota. Did I get a lemon? Service tech says he can't fix it unless he knows exactly what's wrong. I am asking him to check the spark plugs, check the ignition coil...and his response is that they can't just go on a wild goose chase, they need to know what they are looking for. Does this sound reasonable?

Our Accent has just about 86k on it now, back in November it suddenly started running real jerky/rough, misfiring kinda thing. So I was able to drive it to my local repair shop and they found a bad coil pack on #3, so they replaced that and put in new plugs while they were doing it.
Just Saturday we were shopping about 20 miles from home and cranked it up to go home and started doing it again, pretty much identical symptoms, runs out normal at certain RPMs so I knew it was probably same thing...I was able to get it home and then took it in this morning and sure enough now #1 is shot. So they are replacing that. They want about 30$ more per coil then I can order them for myself online so I didn't want to scarf up the money for the other 2 that are still original.

Recently replaced plugs/wires on soon-to-be 10 year old '04 SF 3.5L (157K mi.) for the first time.
Plugs were OE Champion Platinum and all 6 looked identical except for excessive gap of .010 +/- due to all the miles. Replaced plugs with same as OE. Old plug wires looked good, but replaced them with aftermarket wires ( fit was as good as OE). Also replaced plenum gasket.
Problem is: engine runs rough at idle and high rpm and appears to be mis-firing. CEL is off and code reader shows no Trouble Codes stored.

My wife's 2000 grand am 2.4L engine is acting really funny. this is the first problem we've had with it. i was driving it to pick up my kids from school. on the way i stopped and got some gas from the marathon then drove about 5minutes and it started running really ruff lose of power wouldn't go above 30mph seemed like the transmission took longer to shifter to.
i made it to the school as i was about 2 1/2 blocks away. got my kids check the oil and it was really low so i got 2 quarts as it was a gas station in walking distance. i thought it was a lil better but i started driving it and it had the same results. i got it home about a 10minute trip regularly and parked it.
the next day day it ran then stumbled hard. and every time i tried to start it got the same think was like a lock up. it did crank but when it tried to start it stumbled or locked up. i pulled the plugs had some wet threads oil was on the first on and the threads and around the spark plug b4 i pulled it out.
2 of the other plugs had red stuff on them not on the threads though. here are some pictures also i will show a vid of what its doing. i did a compression test and here are the numbers starting with the first one with oil on threads.
190-194-200-190+ compression test with cold engine.
Also smoked puffed up not sure from where yet..

2007 Explorer Sport Trac was misfiring when first started and then would settle down. Now it is misfiring and when I try to drive it, it does quiet a bit of sputtering and has no power. Took it to mechanic he said it would be hard to tell if it was fuel injectors or what.

I have a 2013 Hyundai Azera with the 3L V6. I only use 93 octane gas (as recommended) and only use either Shell or Chevron. Each day, when I get in the car for the first time, I can count on it running rough and having inconsistent performance and some minor sputtering or misfiring (don't know the difference) until the car gets warm. Once it gets warm, all is well. It has 24k miles. Any thoughts on what may be the root cause? Should I change the fuel filter so soon? Does that matter being it gets better when it warms up?I change the oil religiously whenever the computer in the car tells me it is time to do so and use Mobil 1 synthetic.

My 2002 Ford Explorer 4L V6 is running rough I found out why I just don't know what the piece is called because I need a replacement. Mine fell off and fell down the engine and melted quite a bit. Also the part number on my piece doesn't work anywhere, that I have typed it in. Mine has a Ford part number of 1L2U-9F764-AC. Also need to know the proper Ford number. I have a picture I found online with an arrow pointing to the piece I need.

My Nissan Maxima GLE 2000 is showing CEL with code of P1320 ONLY, and the car is running rough/or loss of power. The shop that checked for the code advised that it could be something related to Ignition, and also provided me with the system generated list of reasons for the code. Before I decide to do anything, I wanted to check what option I have to address this in a most cost effective manner:
1) Is there a quick way to check which coil would have gone bad ?
2) Is it advisable to change 1 LH and 1RH at a time, and see if it fixes the problem ?
3) Could it be cam shaft sensor that could have gone bad ? Are there any symptoms of cam shaft sensor failure to isolate it to one way or the other ?

My explorer has been running a little rough, particularly at idle. When I take off from a rough idle, it'll run rough until I hit 25-30mph. I ran by O'Reilly's hoping to pick up a pack of spark plugs and be done with it, ended up leaving with a new MAF sensor. It ran better for about 10 miles (I'm a delivery driver, so I did a lot of stop and go immediately), before it ran even worse than it did before, but at least my CEL finally came on. Took it back to O'Reilly's and they read a MAF sensor code and a catalytic system code (didn't ask for the codes, and now realize that was a mistake).
So today I took it to a muffler shop to have the catalytic system diagnosed. They looked at it for 10 minutes and told me they didn't think it was the converter. They said it seemed more like the EGR valve or solenoid, or the IAC. He scanned the codes again and got multiple "running lean" codes (0171, 0174, etc). The guy said I didn't have a vacuum leak, so I think I can rule that out. Unfortunately, the truck idled fine the whole time so he didn't feel comfortable giving me a definitive answer. He told to to leave the EGR valve hose unplugged for a few days and see if anything changes. I'm thinking about running a bottle of fuel cleaner through it or taking off the IAC and/or EGR and cleaning them myself.
