Ford - Explorer :: 1999 - Misfiring / Shaking / Rough Idle - Engine Light Flashing
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 doesnt stall very often at all. Accelerating I notice way less power and the engine studders. Thats when the engine light comes on flashing. Then remains on solid afterwards.
I brought it to a mechanic friend who read the code and it was cylinder two misfire as well as O2 censor. I replaced the plugs and leads and censor. Noticed the plug in cylinder two had little to no gapping. Thought I had fixed the problem. Vehicle ran perfect. 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.
Passat (B5) :: 1999 1.8t Misfiring At Idle And Battery Light Flashing
I got a 99 1.8t. Here's the deal, misfiring at idle, flashes battery light. alt and battery was checked and there great. it has a maf code, so I unplug the maf and still get the same misfiring. maf was fine be4 i tried cleaning it, now it throws the code. it had misfiring be4 i clean it also. next problem is it stutters and misses if i go wot in 4 or 5 gear and the batt light flashes it doesn't throw a misfire code. Also if I am idling and i floor it, it stutters and misses at lower rpm rage and then is fine at higher rpm range. i replaced plugs and gapped em right, i did a power balance test and the coils all are firing so is the injectors. I don't got vag but i do got a good obd2 scanner i was looking at the data wen car was off and i seen that if i floor it the tps only reads 77.7% . Also my timing says its 12 degrees and idle fuel pressure is fine i checked with a gauge. Pretty much misfiring with no codes thrown and flashing battery light.

99 explorer 4.0 automatic, lately been running weird. Starts up but will stall out unless you let it warm up. And idle drops below 500 rpm. And is really rough feeling. To like 2 or 300 rpm, then will stall but will start right back up. When I changed spark plugs and wires problem stopped for about 2 weeks and now is back. And has no engine code.

What can cause my 99 explorer xlt to have a rough idle on initial start ups?(Its worse in the winter time) And sometime after driving places when i put it in park the truck will cut off. It has the 6 cylinder SOHC if that's useful.

2001 f250 7.3L, 289,000 miles, changed the IPR and ICP, noticed the EBP tube was in two pieces. Would this cause the rough idle and shaking? IT started running rough and would die after a mile or two. Would have to wait 30 minutes before it would start again. That is when a buddy told me to change the IPR and ICP the ICP plug was covered in oil as well as the top of the ICP. So I changed the wiring plug as well. I originally cleaned and changed O-rings on IPR but then it wouldn't start, bought a new IPR and started but runs rough. I just started it with EBP tube removed and sensor unplugged. Idling rough when I press accelerator and RPM go above 2K it levels off pouring black smoke everywhere.

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.

My car has had random misfiring when at idle and has been shaking really bad but once I accelerate and get up to speed the vibrations and misfiring stop but the check engine light flashes for a few minutes. I have changed spark plugs, all 6 ignition coils the intake manifold gasket and both camshaft position sensors. My car has 180K the codes that are showing up are 300,301,303 and 0016.

View 2 RepliesToyota - Camry :: 2002 - Misfiring / Shaking When In Idle Or Going Slowly
Took this car for scheduled maintenance, tuneup on 12/19. AFTER the tuneup, it started shaking when in idle or going slowly. Took it back 1/5, they confirmed it was misfiring, checked a computer code, replaced one of the coils. The misfiring went away but returned, worse than ever, last week (early Feb).
I read somewhere that replacing coils for misfiring can be just treating the symptom, not the cause. What should I do now?
Ford - Taurus :: 2002 - Rough Idle / Misfiring During Operation?
I just recently purchased a used taurus and was experiencing rough idling and misfiring during operation. I replaced the EGR valve, the egr sensor, coil pack, spark plugs, iac valve, as well as check for vacuum leaks near all the hoses. I am a novice when it comes to this, but I was able to change those without issue. The misfiring was fixed during driving, but I still have rough idling. The needle seems to stay in check pretty well and the check engine light isn't on, but the car kinda hesitates and it causes the car to rock when idling. You can also feel the stuttering and rocking when cruising at very low speeds (5-15mph). I've already plugged in a decent amount of money into parts and am running out of patience when it comes to fixing what is a "potential" problem, and it winds up not fixing much.
View 5 RepliesFord F-150 - 1997-2003 :: 2002 V6 Misfiring - Rough Idle
I recently picked up a 2wd 2002 F-150 with a 4.2l V6 that has just over 300k miles. The CEL is on and I'm getting P1131, P1151, P0316, P0305 and an occasional P0301. It has a very distinct misfire from around 1,000 rpm and smooths out between 1,500 & 2,000 rpm, the idle rpm occasionally bounces (sometimes enough to stall), and the idle is sometimes rough.
I have replaced the plugs, wires, fuelfilter, and replaced a leaking PCV hose. As I have changed things the symptoms have improved some but they are still there. While capturing some livedata it kept going out of CL and into OL Fault. When it would the idle quality was crap and the miss was much more significant. I would have to put it into D hold the brake and run the RPM's up to just over 1k to get it back into CL.
After I got done with the data stream at idle, I set the parking brake held the foot brake and put the truck in D then ran the rpm's up to around 1,200 & held it there. The truck stayed in CL but it would cycle between misfiring for 5 - 10 seconds then clear up and run smooth for 20 ' 30 seconds, every time it cycled there was an audible click that could be heard. Also, the AC was off the whole time.

Ford F-150 (2004-2008) :: 5.4 3v - Rough Idle / Stalling And Misfiring
I recently bought a 05 f150 with 5.4 3v and 195k miles needing some work. Ran great, just had a code for timing over retarded. Originally it had a cracked timing cover, so i took it off to replace and found broken guides and bad tensioners on timing. I installed new guides, chains, and tensioners, and cleaned phasers, and put back together only to find it ran terrible and had a phaser rattle. I then went in and installed phaser locks, which took care rattle but not the running issues. I can not figure it out.
ISSUES: My issues almost mirror what is said in this thread here, but this issue was never solved. [URL] ....
My issue is when started cold it starts right up, idles ok, runs ok, although a bit sluggish. Once its warm it stalls at idle, shudders when giving throttle in overdrive, and if you kick it down it will continually backfire, and slowly accelerate... it kicks down but acts like its only getting 1/8 throttle, just kind of hangs at the same rpm and slowly climbs in rpm. Sometimes it wont backfire as much, and sometimes the check engine light flashes. After it stalls at idle and you start it back up it sounds like it shudders/backfires for a split second then starts.
It is throwing many engine codes, but most are from the phaser locks. Throws code for timing over advanced on each bank (phaser locks lock them fully advanced), cam timing codes for each bank, and then a code that doesn't have to do with the timing, P2106. I am going to run some live diagnostics on it today and report back but I am fully at a loss.
Ford Ranger / B-Series :: 2002 - Rough Idle Codes / Cylinder 2 And 3 Misfiring

I drove home Saturday morning from work with no issues. Car sat until Monday night and as soon as I had to stop at a light it was idling very rough where the rpms were jumping 3-400 up and down. I make it to work and on the way home I experienced the same idling issue along with some misfiring. I scanned and came up with the following codes. I have no CEL. I had my APR flash, Forge Intake, Turbo back exhaust all installed 2 and a half years ago. I have owned the car for four years never having replaced the DV or PCV. 87,000 miles.

Ford F-150 (2004-2008) :: Misfiring - Rough Idle - Got Codes P0340 / P0344 / P0345 And P0349?
I recently purchased a Ford pickup. I bought a 2004 F-150 with the 5.4L 3V engine. I have only driven it for about 300 miles so far and am having problems. The engine has 200,000 miles on it. I have read several posts on here about the cam phasers which I believe that I may have some issues with. The engine will run good when cold, on the road, etc. The engine does have a slight ticking after it warms up (cam phasers?). When I come to a stop after the engine is operating temperature, the engine will start to miss and shudder and all 4 above codes come active and are also pending (8 codes in total).
All 4 codes are logged at the same time. I have replaced both cam position sensors, both sensor ends and terminals for cam position sensors, checked wiring around rear of engine (does not appear to be rubbed through), all plugs were replaced, and all COP boots are good. Is there anything that can cause these codes that may not be the actual cam position sensors, ie. VTC, COPs, cam phasers? What pins the cam position sensors come to on the ECU (so I can ohm the entire wire harness)?
Also, if the engine is missing with the codes active and I rev the engine up it will come back to idle and run great. The engine never dies out, just runs horribly. I have also unplugged each sensor with the engine running which has no effect on the way it runs.
