Passat (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.

Accent MC (2006-11) :: Stalls When Idling - No Check Engine Light

So, I have a 2011 Hyundai Accent. It drives great. Until recently.

My wife noticed that it was cranking a little longer than usual before starting. Then, one day, I noticed it. So, I stopped the car and restarted it to see if it would happen again, and listen more closely. But, all ti did was crank.

I became upset and went in to do some research and make some phone calls. I came back out and voila, it magically worked fine again. Weird, I thought.

A few days later, no incidents. We go to the grocery store. On our way out, it cranks longer. This time I'm not going to restart it, I think. So, I start driving and everything is great. Except...it suddenly wasn't accelerating. It felt like it was in neutral for like 100 feet or so, then back to normal. We're making plans to take it into the shop at this point.

The next day, we go out to get coffee. Car drives great. On our way out, no problems. We stop at the red light, and it stalls. I have to push it into a parking lot and call the tow. Strangely enough, it starts again ten minutes later, and runs fine.

The stalling and being unable to start for tenish minutes phenomenon has happened three times.

We took it to the shop, it actually did this as I was filling up gas--stalled. I pushed it into a space and waited a few minutes, bam, it started up fine. The mechanic told me that the engine light had been reset. He couldn't figure it out. Said everything looked great.

So, the run down is this:

-My car stalls when idling, but only after it has been driven some, stopped, and restarted without a lot of time passing--like when you're coming home from the store or something, after it sits for 30 or 40 minutes.

-Once stalled, it will not restart again until a few minutes have passed --something like five to ten minutes.

-There is no check engine light. Fluid levels are good. Connections and whatnot, according to the mechanic, looked good.

-When it stalls, all the electronics stay on and work. The oil light and engine light pop up (like this key is in and turned part way), then it all goes away when the car restarts.

-the computer says that it was reset after it does this.

Avalon 2005-12 :: When Idling Motor Seems To Be Very Noisy - No Check Engine Light On

My Avalon has 55,000 miles on it. when it is idling the motor seems to be very noisy. to me this isn't normal my service rep says there should be no problems if there is no check engine light on.

Should not be as noisy with such low mileage. dealers says if there is no problem and that is the way it is they will charge me for the diagnostic fee. seems like it's not right the way it sounds so what is everybody's opinion on this issue. Oil level is up and very good so just wondering if it could be very variable valve timing solenoid making noise.

Mazda :: Check Engine Light Blinking And Idling Rough Almost Cutting Out

Today I went to the gas station and after I gased up and turned the car on my car started idling rough, almost to the point of cutting out. I started out on the road and my check engine light started blinking. After some time it stopped and just stayed on. The whole front end shakes pretty bad when at idle. The car has trouble accelerating till roughly 35-40 mph then seems to ride ok. I'm not very car knowledgeable, but I do take care of my car. I know I need to replace some of my hoses and spark plugs soon, but am worried that it may be more serious.

What I would like to know is: 1. What could possibly cause these issues and 2.

Santa Fe (CM - 2007-12) :: Check Engine Light Came On - Vehicle Jerks When Idling

My 2007 Sante Fe had problem this week. Took 6 attempts to start engine, then ran smoothly the rest of the night. The check engine light came on while trying to start vehicle.

Next day I changed the spark plugs but now find that the vehicle jerks when idling. Runs fine when going but jerks and bucks at stop lights and stop signs. Just added fuel injection cleaner to see if that may support the situation.

Engine light has come back on again since resetting. I have read several suggestions on internet regarding leak in vacuum line, Coil Pack damage due to faulty hose, even faulty 02 sensor.

Malibu :: 2001 - Check Engine Light Came On / Idling Really Rough And Slow To Shift

2001 with the 3.1 6cyl. First thing that started this nightmare is I was noticing a bit of a hiccup after driving for a couple miles. We've only had the car a few months and not sure what maintenance was done so we thought maybe it needed a tune up. Before I got the parts the check engine light came on so I went to parts store to get it read, it was P0302.

Did the wires and plugs and it got worse, the code wasn't p0302 now its just p0300. But after the plugs it also started idling really rough and would be slow to shift. Once it tacked up high and wasn't speeding up. That was only once tho. Also now it has no power its like driving a 2cyl ...

Anyway we decided since the first code said 2 we replaced coil 2, no luck..ok, fuel filter and fuel injector 2, no luck. Also has cleaned various things Im not sure of the technical name for..sensors and air filters and other things.

None of this has worked the car still idles very bad and doesn't have the power it should have. Also cleaned things on fuel rail(?). He is in the process of replacing the crank sensor as someone said if it was all the way bad it would throw a different code but it may just be faulty.

Ford Escape / Hybrid :: 2010 - Check Engine Light Came On / Randomly Went Off While Idling

So my wife was driving our '10 escape xlt and the engine light came on and it displayed the 'check engine' message on the screen. It has 86500 miles and luckily no problems yet. The only thing that has changed was she accidentally put super premium gas in it the other day. The light came on and after she drove it home (about 10-12 miles) and it sat for a few hours and i drove it about 20 miles it randomly went off while it was idling.

I shut it off and let it sit for 20 minutes and then let it idle for a few and it never came back. It has been running ok. We definitely drive it a lot as she works day shift and i work nights. I'm just trying to make sure there's nothing wrong with it. I got a bulletin a while back about the intake getting moisture in it. I didn't know if maybe this could be the beginning of this or something else. This is a whole new territory for me as i consider my 91 f250 'new'

Ford F-150 - 1997-2003 :: Idling Rough And Check Engine Light Came On After Running For About 20 Minutes

I replaced the heater core in my truck this weekend. The only thing I was worried about was pulling the dash. The truck is a 1998 f150 with the 5.4.. Everything went fairy well and decided to replace the AT Shift cable as well. Got everything put back. Truck runs, no leaks, no antifreeze smell. After running about 20 minutes, it started idling a little rough and my check engine light came on.

The codes are p0136, p0156, p1131, and p1151. I know these are related to the OS sensors. My question is could it be as simple as I miss an electrical connection when putting the dash back in? Was thinking possibly somewhere on the passenger side under the kick plate or possibly something while hooking up the heater hoses? Maybe even a ground that didn't get connected back when putting the das back in?

Kia - Rio :: 2009 - Misfiring And Flashing Check Engine Light

Yesterday out of no where my rio started to misfire so i immediately took it into autozone to have it checked. when doing so the check engine light was on, but solid.

The tests came back with P0300, P0301, and P0302 or 3. I cant find the papers, but its 3 cyns that are misfiring. The guy at autozone suggested i try changing out the plugs first since its cheaper and has been known to fix this issue.

The second I bought the plugs I went home and changed them out. once finished i started up the car and not only was the car still misfiring, but the check engine light is now flashing... I did notice one thing when changing the plugs.

If facing the engine the second coil from the left had a bit of what looked to be rust. i was able to wipe it off with ease. What my next move should be?

Camry :: 2009 - Check Engine Light On / Error P0500

Currently I haven't been tweaking anything to my car after driving to go and home I left to go get something to eat and after driving for a few min out of nowhere the engine light, brake and abs comes up. So I freak out a pull over to the nearest gas station and turn my engine off for 2 min and turn it back on and this time only the engine light come up. So I drove to autozone to get it scan and error p0500 comes up. Which means short circuit, vss and poor electricity something I am not exact but is it serious? Like I am freaking out right now.

Camry :: 2009 - Check Engine Light Is On And O2 Sensor Dead

My 2009 Camry check engine light is on. Dealer said the two O2 sensor both are dead and need to replace. After dealer reset the check engine light I have driven two days for 50 miles and the check engine light doesn't come back. If the O2 sensor is bad how long does it take for check engine light on again? Is it possible the check engine report on by mistake since two O2 sensors got bad at the exact same time is really rare.

Elantra HD (2006-10) :: 2009 - Check Engine Light With 3 Codes

My check engine light popped up the other day and when ran, 3 codes popped up: p2414, p2195, and p0170. From what I could gather it looks to be the O2 sensor is bad. This would be the one on the exhaust manifold, correct?

Also, what would cause the o2 sensor to go bad in the first place? My 09' has roughly 65k miles.

Toyota - Prius :: 2009 - Check Engine Light Suddenly Came On

I own a 2009 Prius (4 years and 4 months old) with about 33K miles on it. Last Sunday while driving the Check Engine Light (CEL) suddenly came on. I made it home and started digging for possible causes - everything from a loose gas cap to a failure in the water pump for the inverter to a 12V battery nearing the end of its life. I've eliminated the water pump for the inverter as the source of the problem since, when I put the Prius into "Ready" mode, I can see movement in the fluid reservoir (when the gas engine is not on) indicating that the pump is working (it had also been replaced under a recall on that water pump a couple of years ago).

I'm down to a loose gas cap (which I checked and tightened) or the 12V battery as possible problems. I've tightened the gas cap but the CEL won't go off and I'm about to replace the 12V battery. Will that clear the CEL? I'm going to take it to a mechanic on Friday morning (my first opportunity - until then it's sitting in the garage) to get a code readout. Could this be something more serious? I mean the car is under 5 years old and has only 33K miles on it! What else could be causing the CEL to light up?

Ford F-150 (2009-2014) :: 2010 5.4L 3V - Check Engine Light On

2010 F-150 5.4L 3V gas, 6 speed auto, 2WD.

I got a Bully Dog GT Platinum Gas with plans to purchase a tune from 5starturning. Was messing around and loaded the built in 05-10 Ford Gas tune in Bully Dog... all went well.

Take it for a drive around and next thing I see is my check engine light is on so back to the house and revert back to the factory file... again, all went well.

No such luck; still have the check engine light and the Bully Dog says there are no DTC codes. Needless to say, I'm a bit freaked out.

I have tried uninstalling the Bully Dog tune and reverting to factory file and still no luck.

I think I would feel better about it if I could just find some comment saying "this is common just unhook the battery and reset and go on your merry way".

Ford F-150 (2009-2014) :: Check Engine Light Intermittently Comes And Goes

Purchased certified pre owned 2009 f150 may/2010 24,000 mile. The check engine light intermittently comes and goes. It seems that its either cold temperature or related to filling the gas tank. The first time it appeared I drove 100 mile then the truck sat over the weekend and went back off when started. The second time had serviced for the check light and the dealer diagnostic pin pointed P0304, P0305, P0300 and P0316 and replaced cyl 4&5 coils.

Prior to the replacement of the coils the truck averaged 18.2 mpg since the repair the mpg dropped to 17.6 and now at 17.2mpg. Had the truck in again and the light was on when I made the appointment but went back off when I went to the dealer. They said the reset the computer. The light twice has since went on and then back off after a couple days. The only observation is that the outside temperature on both occurrences has been below freezing and that I had filled up the tank.
