Ford Ranger / B-Series :: 2002 - Rough Idle Codes / Cylinder 2 And 3 Misfiring
I have an 02 ranger xlt 3.0, it started having a rough idle, codes say cylinder #2&3 misfiring, changed plugs, wires, coil pack, didn't work, still same code, checked injectors on right side, all 3 had ohm reading of 15.8-16.5, the injectors were clicking like they are supposed to, sprayed carb cleaner around the intake ports, didn't change the idle at all,what else can I check or do? with out tearing the engine apart, unless of course I have to, the truck has been very good to me, it's got 205,000 miles on it, I need it to last at least another year...

I've got a 2000 Ford Ranger, manual 4 cyl. When cold, she's been stalling out. It happens very reliably when I come to a stop and put it in neutral (or put the clutch in). Only when she gets warmed up does it stop. Check engine light has been on (for a long time) saying the TPS sensor is out and the 4 cyl. is misfiring. I replaced the TPS sensor and it had no effect on the problem. A friend recommended changing the oxygen sensor.
View 5 RepliesFord Ranger / B-Series :: 1998 - Which Cylinder Misfiring
I got this 98 Ranger 2.5 that I've done a tune-up on less than 30,000 miles ago. I changed plugs, wires, and both coil packs. Timing belt, thermostat, fuel pump, fuel injectors are all recently changed too within a year or two. Fuel filter and air filter I change every 30,000 miles. The truck runs as great as a 4 Cylinder will run. It's at 344,000 miles but the engine was changed once so it probably has over 100,000 miles on it. There is just a slight miss you can hear through the tailpipe but it's not severe enough to be picked up by the Check Engine Light. In fact, even when the coils were totally gone it never put up the Check Engine Light. I can tell when a coil pack is going out on this because it's done it several times so I usually just change them with the tune-up. It's only a slight miss some people may not even notice it. I was just wondering is there any way to track down where the miss is? I tried looking under the hood in the pitch black and there's no plug arcing.
View 1 RepliesFord Ranger / B-Series :: 2002 - Running Rough Like Misfiring
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
Nissan - Maxima :: 2002 - Zero Power / Misfiring On Cylinder 6
I have a 2002 Nissan Maxima GLE. I had had problems with it misfiring. It said it was misfiring on cylinder 6. Put all new spark plugs on it, same problem. Put new ignition coils, still same problem. Had it checked by several mechanics. NONE of them could find why it wasn't getting power. Then about 2 weeks ago I was driving it home & it died. Got it started & it drove less than a mile & died again. when it died that time, I suddenly had NO POWER to anything in the car. Lights don't work, no horn, no radio, no beeping when key is inserted--NOTHING. if I let it sit for a day or two, it will start clicking & then interior lights will come on--until I put the key in it & turn it over. Then I am back to no power. It does not crank or anything when I turn the key over. I have had the battery checked and they said it is still good, had 100% charge--even after being off the car for over 24 hours. I have been wondering if it is the ignition switch or starter...

I have a 2002 ford ranger xlt 3.0 i just rebuilt the entire motor about a month ago and was having a high idle problem for the longest time. turns out i had the iac on backwards. but now that it idles down around where its supposed to it has a rough idle has a little shake to it. starts up right away but when i drive down the road around 3000-3500 rpms its missing on cylinder #3 from what the code I am getting "multiple cylinder misfire, #3 cylinder misfire" I've replaced plugs and wires. camshaft pos sensor. I am getting 65 lbs of fuel pressure. spark on all cylinders. I am really at a dead end here. Also every time I take the plugs out to look at them they look brand new.
View 14 RepliesFord Ranger / B-Series :: 2002 - Cylinder 2 Misfire Code / Idle Rough When Warms Up
I 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.

View 5 RepliesFord F-150 - 1997-2003 :: Misfiring Cylinder 3 And 8
Trucks throwing codes for cylinder 3 and 8 misfire. I pulled the plugs and both were covered in oil and cylinder 8s electrode was literally gone. so I replaced the plugs and within 5 miles it was missing again. so I replaced all plugs, all wires and coil packs. cylinder 8 plug had fouled out. Its a 4.6l 99. I have a mild exhaust leak where the manifold connects to the downpipe. but not bad enough I feel it should matter. it runs rough until about 3k rpm and then it kinda straightens out.

I had a misfire and my CEL came on had it read and it said cylinder 4 was misfiring and that there was a misfire in the first 1,000 RPM's. I replaced the COP and plug and now I'm getting terrible MPG. I tried to reset the PCM by removing the Neg. battery connection and it seemed to work for 4 days now my MPG has gone bad again. It seems to run smooth/good.
View 1 RepliesFord F-150 (2004-2008) :: 2005 - Cylinder #5 Misfiring?
Had a miss in the #5 cylinder on a 2005 F-150 5.4 Triton. Had it hooked up to see which code was given and the tech said that #5 was the culprit. Taking no chances, I purchased a new plug and coil pack. I installed them and it ran great until I got up to around 70mph and then it started dong the same thing it was doing earlier. I took it back to the place that checked the codes and it came back as the #5 cylinder misfiring again. I am not sure how this is possible after replacing the plug and coil pack. Is there some way that the plug that fires just ahead of #5 is fouled out and causing the #5 cylinder to get too much fuel transferred to that cylinder? Or is there a possible short somewhere causing that cylinder to misfire and ruin the coil pack? I am stumped on this for the moment anyway.

2004 5.4L ... Codes indicate a firing issue on #4 cylinder, figure it's the coil pack. They bought truck used a few years ago and plugs have not been changed since they have owned it. I was going to change plugs while I was under the hood. While checking threads on this engine I picked up on plugs being a major job unless you know the tricks. So what tricks do y'all have up your sleeve to keep from breaking plugs?

Happened a few times on me lately. While pulling towards the top of 5th, I'll start to see the check engine light briefly blink as if the car wasn't sure, then at the top of 5th, she'll start misfiring on cyl 2 and 5. It's only during the long haul pulls that this occurs. My plugs and coils were all changed about 1k miles ago.

Ok I got this truck from my mother-in-law for free with a blown head gasket cylinder 6 driver side. I did the replacement had the heads machined put it all back together by the book. Now I can't get it to fire on all 6 cylinders only 5 I think. Thought maybe bad gas (it sat since late November) put 5 gallons (over double the gas) fresh gas and half a bottle of b-12 chem tool. Dubble checked all plugs wires connections (coils plugs wires all new). I drove for about 10 miles oil pressure and temperature stayed perfect but no change in running truck shakes a lot and no real power. Don't sputter or backfire no engine codes other than imcr bank 2 open. Engine is 4.2l v-6 170k miles.

Touareg :: Put In All New Plugs / Cylinder 5 Is Misfiring
I have a 2008 Touareg 2, V8, 4.2L.
I bought it used (~95k miles) and almost immediately had an issue. #5 is misfiring. Since then, it has been in the shop 10-12 times with no resolution. Here is what I have done so far:
Put in all new plugs/coils sent the ECU to SIA electronics in Chicago for testing - no errors replaced the injector with a new injector on #5swapped #1 for #5 (plugs/coils)checked the harness (dealership said they did this, but not sure if they did or are just tired of me)
Through all this, #5 is still misfiring. The dealership is out of options, suggesting that the ECU is faulty and needs to be replaced ($1600) or they need to swap the #5 injector with #1 to see if that is the issue (~$1000+). Neither of these options sound reasonable because a) the ECU was already tested and b) the injector is brand new, yet the exact problem (#5 misfire) has persisted before and after the injector replacement.
Passat (B6) :: 2006 2.0T - CEL On And Cylinder 3 Misfiring
My dad has 2006 passat 2.0T. In December 2010 he went overseas. During his absence the car was parked in garage and not in use.
So one day I decided to start the car and as soon as I turned it on the car made this noise and check engine light came on. Took the car to a private repair shop and found out the cylinder #3 was misfiring. The tune up for this car was due so I had all four spark plugs changed and the car ran fine for few days. Then couple of days later it started making the same sound and this time around the coil for cylinder #3 was replaced.
A few days after that check engine light came back and this time it was blinking and the engine was struggling to run, took it again to the workshop yesterday and this time another coil not sure which cylinder was replaced. (all this is done at a private workshop). I have a hunch that the car is going to run fine for a day or so and the problem is going to come back
I never had any major issues with it up until now. Bought this car new in 2006 from dealer. I am afraid that this might be a start of a downhill roll from here on I will drive the car tomorrow and see how it reacts.
