Ford F-150 - 1997-2003 :: 1999 - Service Engine Soon Light On Sometimes At High Rpm Or Rough Erratic Idle
My trucks symptoms include a illuminated service engine soon light, sometimes a high rpm idle, and sometimes a rough erratic idle. When a scan was done it indicated the oxygen sensor was defective. The issue is: which specific one (there are multiple oxygen sensors) or how could I check or determine the faulty one for sure. I am trying to economize and replace only the bad one myself if possible. I own a good multimeter, can it determine the bad one? 1999 F-150 4.2 Litre V6 oxygen sensor dillemna....

I just had my 04 5.4l engine rebuilt. Ive driven it about 500 mi and it started running rough at a stoplight. I tapped the accelerator and it started running good again but service engine light came on. I pulled the codes and they were P0022, PO345, P0340,and P0430. It has done this several times now. Everything was replaced including the phasers, except for the camshaft sensors. Could they cause this problem?

View 14 RepliesSaturn - Vue :: Service Engine Soon Light / High Idle Condition
I have a 2002 Vue with an annoying "service engine soon" light problem. When I first took the car in to have it scanned, codes 171, 172 came up, which were "Fuel too lean Bank 1/Bank 2". It also has a problem with a high idle condition where the idle will creep up to 2000 rpm when parked, and a vacuum leak. My mechanic fixed the vacuum leak and replaced the gaskets on the intake manifold plenum, reset the light, gave it back to me and within twenty miles the light came on again. It only has 20,000 miles on it....

My car is idling rough and the Service Engine light blinks on/off continuously. I ran the codes and they are P0301, P0401 and P1258. What this could be? I changed the plugs, wires and ignition coils about a year ago. Catalytic converter was replaced around the same time but the O2 sensors hasn't been changed. Could that be the cause?

This is my brother's 02 SE. 140k miles. 4cyl. He claims that the car is beginning to idle rough when he is stopped at a stop light and the AC is on. If i replace the spark plugs should that do it? I'm pretty sure it doesn't have spark plug wires cus that's what my dealer parts dept said. Motor mounts were replaced around 70k if that matters. The vibration is directly related to the AC being on.
I am also going to replace the serp. belt because there's a belt squeak when the motor is cold.
Elantra MD (2010-15) :: 2014 - Shakes Like Rough Idle When Stopped At Light After Changing Battery
After changing my battery my car seems to do fine as long as you are going down the road but as soon as you stop at a light it like shakes like a rough idle but the RPM's don't move and it never dies. If you have a lot of pull (heater, lights, radio etc) on it, it seems to get worse. It was in the shop for 65 days with engineers looking at it an all they say is its normal. I say this isn't normal because it wasn't doing this until I changed the battery.

Just bought a L/Certified pre-owned 2013 ES 350. I am shocked at how much the car vibrates and noise increases when stopped at a light or stop sign. I tried a 2015 ES 350 and the same thing occurs!! The dealership technician says everything is operating "to specification". This is a disgrace for such a high-tech, luxury car.

I have a 1999 F-150 w/ 4.2 V6. and auto trans, truck has 219,000 miles on chassis but only 25,000 on engine and 10,000 on trans. I've been getting obd codes p0705 and p0715. I replaced the position sensor on outside of trans. but I continue to get the codes off and on again. I noticed that the O/D "OFF" light on the shift selector blinks simultaneously when the "service engine soon" light comes on. I've noticed that there is no low gear unless I have it in D from a dead stop, and not even when downshifting manually.
View 1 RepliesPassat (B6) :: Check Engine Light / Rough Idling When Stopped
Weird problem on my Passat today. First the engine light came on...followed by rough idling. It smooths out when moving, but rough again when stopped. Noticed that turning ON the AC makes it a little smoother...but when you turn off the AC, resumes the rough idle.
Already made an appt with the dealer tomorrow...but wanted to see if this problem is familiar to other owners. Either way, I will update once the dealer finishes diagnosing the problem.
The car has been perfect up to 30k miles...now 2 problems in the last month.
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.

View 2 RepliesFord Ranger / B-Series :: Rough Idle - Check Engine Light Starts Flashing
My 3.0 with 216k miles has developed a rough idle and it progressively got better with new parts and cleanings. On startup it revs up to 2k then back down to 600. If I let it idle for about 8 or so minutes my Check Engine Light starts flashing. If I drive about for a little bit it stops and is just fine.
While the light is flashing I get codes P1000, P0305, P0306, and P0316. Which are OBDII Monitor Testing Not Complete, Misfire detected in Cyl 5, Misfire detected in Cyl 6 and Engine Misfire Detected on Startup (First 1000 Revolutions) respectively. Any other time the truck runs like a dream. Gets 20 city and 29.5 highway.
I cleaned my Mass Air Flow, replaced my Idle Air Control, SeaFoamed throttle body and vacuum lines, brand new coil pack, new wires, new plugs, new fuel filter, I've only ever run 91 octane, Chevron with Techron goes in at every oil change and B12 every other and I just ran 3 bottles of Lucas fuel injector cleaner.
Ford F-150 - 1997-2003 :: 2000 V8 Running Rough At Idle And Check Engine Light On
I started out with my 2000 F150 with a 5.4 V8 running rough at idle. It would idle way down slow and then rev up a little over and over. On a couple of occasions it would even die when in drive or reverse. I did finally get a Check Engine light so i put it on my diagnostic program to see what was up. Here is what I got:
P1151 Lack of HO2S21 Indicates Lean
P0171 System Too Lean Bank 1
p0174 System Too Lean Bank 2
After doing some reading up I checked all my vacuum hoses and cleaned my mass air flow sensor. I then got the same codes again after a few minutes of running. So I went to the next thing that was recommended, the upstream bank 2 O2 sensor. After changing it the truck ran fine for a couple of days, no issues. Then all of the sudden it idled a little funny again and I got a Check Engine Light again. This time:
P0171 Bank 1 Lean
P0174 Bank 2 Lean
P0300 Random/Multiple Misfire
I reset the light to see if I would get the same again later. Before the light came on again I filled my truck up with gas and it seemed to be running pretty good again. Then a day or so later it set the light again. This time:
P0171 Bank 1 Lean
P0174 Bank 2 Lean
P0136 O2 Circuit Malfunction Bank 1 Sensor 2
P0156 O2 Circuit Malfunction Bank 2 Sensor 2
P1131 Lack of Switches HO2S11 Lean
P1151 Lack of Switches HO2S21 Lean
I went ahead and drove for a few days as it had gotten really cold here and I didn't feel like messing around in my shop since it isn't heated. A couple days ago I needed gas so i filled up again. Suddenly the problem was gone again. Truck ran fine idled fine no missing or odd idling at all. That lasted a day or two before it started acting a little weird again. At that point i was down about 1/8 of a tank from full. I have read that there can be issues with the fuel pump.. I am kind of wondering if that may be it now. But I haven't had to deal with this sort of issue before so I am unsure what to check next. The truck always runs fine off idle, it only seems to have the issue when it is idling. I had reset the codes the last time and i have the light on again now. I haven't checked it yet but I am sure it is going be some combination of what i have had in the past.
I have read that the IAC valve can be an issue as well. I had a problem with mine sticking a couple years ago and when it would do it you could just tap it with a wrench and it would idle up. But it never died like it does now and it would also idle a lot slower than it does. Back then I cleaned the valve and had no more issues with it. The truck has always had times when it would act weird at idle usually after slowing down after being at highway speed. The current issue happens at all temps cold or hot.
Passat (B6) :: Engine (MIL) Light On - Very Rough Idle
When exiting off the freeway and stopping at the light, my car felt as though it was bucking and idling very rough. I put the car in Neutral and it subsided a bit but the lit gauges were pulsing with the idle. It felt as though the car was going to die. I put the car back into Drive and it drove fine. I pulled over and shut the car off. There were no warnings or any other indicator lights on during this time. After shutting the car off and leaving it for a couple mins, I started it back up and the engine light was now on steadily. The rough/bucking idle was present as well. I ended up driving the car to the dealer where it is now being diagnosed and I haven't heard back.
View 6 RepliesTiguan :: Idle A Little Rough - Check Engine Light On
New 2012 Tiguan S with a manual, 800 miles and the check engine light comes. Seems to idle a little rough, at least the idle seems to fluctuate a bit. The real disappointing part is I took it in to the dealer expecting an easy fix within an hour, its now been at the dealer for 2.5 days and they'll have it over the weekend as well. They tried putting several parts in it, still didn't fix it. They called VW who said pull out the new parts, put back the old parts, and apply some software update. Dealer did that, still not fixed.
