Golf/GTI VI :: 2009 GLI - Running Rough / Engine Seems To Chug A Little When It Was Cold
Jun 6, 2011
About a week ago I purchased a new K&N air filter for my '09 GLI (6spd stick & all factory options with 55,000k on the odometer). Outwardly the vehicle seemed to run better (although a new clean air filter of any type will make a vehicle run better) however, 2 days later I noticed that the engine seems to chug a little when it was cold. Not missing like a plug wire off but a chug where it surges forward then holds back continually until the engine warms up. This persists today. I've also noticed a little bit of a rough idle. I've re-inspected my installation and nothing seems to have come loose and the filter fits perfectly.

We have been having issues with my son's 97 Sierra running rough when it is cold/damp. It feels like the engine is missing.
Today, which is warm and dry, it started running really bad and it was all he could do to limp it home. It seemed like it wanted to idle fine but when he tried to rev it up the tach would start jumping and it seemed like it was missing.
Could this be a bad cap/rotor? The engine has 200,000 miles and we've never changed the cap/rotor. I changed the plugs/wires probably 100,000 miles ago.

I have a 1990 3.1L, multiport fuel injection (NOT sequential FI), which runs very well most of the time. However, when I cold start it runs rough (misfire) for about 1 minute (no throttle) or until acclerated. The is no misfire when running normal, but it might be running a little rough when stopped at a traffic light (in Drive, foot on brake).
I put new plugs and wires on, but it did not affect this problem.
I am not using coolant, or oil, the plugs that were removed were somewhat worn, enough that I expected to notice a difference after they were changed.
I have not yet (1) cleaned the MAF, (2) checked carefully for vacuum leaks, (3) checked for leaking injectors.
Since this is a 1990, OBDI, I can't say which cylinder is misfiring or how the fuel trims look etc.

I have a 2009 Jeep Grand Cherokee. Engine is running rough. Check engine light comes on. Code is P0152. The code is defined as high voltage on the front o2 sensor (bank 2). I hooked up the scanner again and checked the voltages. Both O2 sensors on bank 2 are never making it above 0.1V. That seems to contradict what the DTC is telling me. Is that somehow related to the fact that it is not going into closed loop? I'm a little confused.

I have had some slight rough running with a cold engine and stumble <2000rpm. Finally it tripped a CEL which was read as a misfire code.
The mechanic swapped the coil and plug(recent) and no change. He did a compression test and air blew out the exhaust. So.......the car needs a valve job which entails motor removal and fixing the head and reinstall. He rough estimates this at $2000 and rate is $65/hr.
He mentioned looking at pistons and may be a bit more if rough.
This car well maintained (170,000 miles 2005 Legacy turbo wagon with manual)...

Our R32 has 2428 miles- and today the check engine light came on and it started to run pretty rough, babied it home and the the light was blinking when I turned into the driveway.. I know that booklet 3.2 in the owners manual is diagnosing catalytic converter issues...I have always used super unleaded, it hasn't even reached the halfway point of the first service.

Regarding my problem (outline below):
>> Went for a refueling stop, and thereafter proceeded onto the highway
>> Approx. 500m into the drive onto the highway the car started jerking and running rough with an initial puff of smoke (none thereafter)
>> Immediately after this initial jerking/shuddering there was a significant increase in fuel consumption i.e. from a familiar 8.2L/100km to 18L/100km in the cruise
>> We continued driving not knowing what it was (I suspected a spark plug may have stopped working)
>> Pulled up at the gas station to observe what went wrong inside the engine bay - no signs of any leaks, fuel sprays, etc. but only that the engine was shaking
>> I checked the rear of the car while the car was idling and observed a pulsating sound...some light smoke and a fuel-rich egg-like smell
>> Asked around and I was led to think the catalytic converter was ruined, so the next day I had the catalytic converter cut out
>> After removing the catalytic converter the problem persisted...although the engine operated with slightly less flow resistance
Attempt at diagnosing the problem
>> My wife called in a technician from BMW at Canal Walk to come have a look and what errors were flagged
>> The tech ran the diagnostic and no fault codes were indicated, except a few short circuit faults due to my incorrectly placing -ve on +ve when I tried to charge my cars battery with jumper cables
>> He proceeded to ask if we changed the spark plugs, I said yes. He then looked at the oil on the intake manifold and said there could be a torn valve on the intake manifold and that air that is not measured by the air mass flow sensor is entering the engine, which is causing the car to rev hunt (this problem of rev hunting has been with us for a while). The engine also shuts down uncommanded at stops and sometimes between shifting gears with the subsequent loss of power steering (very dangerous!!)
>> We also had the O2 sensor replaced a month before this occurence
The images attached (#1- #3) are marked up to indicate the component I am referring to.

Went to Cape City VW in Cape Town and the part number for that orange thing/diaphragm is 06A 198 205A 'Repair kit for valve'. Is this significant? The car sounds as strange at idle...as if has noisy valves. I can upload (if there is an option) a sound clip of how the car sounds if this assists.

It levels off and idles fine after about 10-15 seconds but sometimes it idles so rough I think it's going to stall.

So my temp light comes on in my 2002 gti 1.8t. The light comes on with the engine cold and not running, just keys in. I replaced the temp sender and the fan switch. I already checked the fuses, still good. The only thing i can think of now is the relay. There is plenty of coolant in the system as well. And I am not getting any CEL.

I started my car this morning and drove to work. It's not that cold. I heard knocking sounds coming from the engine at a stop light. I lightly tapped on the accelerator to hear it better. My commute is short (3 miles), so I gingerly cruised there. I didn't try to accelerate and it didn't seem like I was suffering from loss of power either. I opened the hood and let it idol at work and couldn't really hear the knocking sound.
I downloaded the code when I got to work. After that I started the engine again and it sounded pretty normal. I'm due for my oil/filter change (~5500 miles).
Here are the codes. Any reasons to worry, or is this an one-time thing?
2 Faults Found:
001322 - Camshaft Adj. Bank 1 Intake
P052A - 001 - Cold-Start Timing not Reached
Freeze Frame:
Fault Status: 01100001
Fault Priority: 2
Fault Frequency: 1

I have a 2008 MK4 2.0 with only 53,000kms. At 40,000Kms I put new OEM spark plugs.
Just recently, every morning when I start the engine is sputtering and rough running. The engines want to die but I give a little gas, and run rough like it is only firing on two or three cylinders.
When it gets to the normal operating coolant temperature it runs without any problem and I can use the AC. Its only give me this problem on the first start of the day.
Does not have any MIL light on the instrument panel. I scan it with VCDS-Lite and do not found any fault codes. The only thing that's come to my mind is to change the Green Coolant Sensor.

I have a 2009 honda accord, v6, auto, 46k. It has recently started to chug, most of the time, not always. I feel it in the gas pedal. Kind of a jerking, hesitation chug while accelerating. It only chugs between 20-40 mph, disappears after that. Someone suggested a spark plug problem, but I can't imagine it's that since it disappears after 40mph. Could it be a transmission problem?

I have a 2000 Honda Accord Ex that began to run very rough when cold. After warming up it seemed fine. Now the car runs rough whether hot or cold. The car only has 23,000 miles on it. The cap, rotor, and wires all appear to be good.

My 2000 Accent 1.3 has developed a problem recently: starts fine and revs freely and smoothly when parked. When I pull away it will get very rough like it's firing on only 2 cylinders or so, at certain points during the rev range rather than continuously. Very juddery.
After a minute or so, before the engine temp is even up to normal operating temp (according to the dial) it runs perfectly. When I start it up later the same day it's fine. It only happens the first time in a day that I use it. The more days I go without driving it the worse it is.
In the last couple of years I've changed spark plugs (always in good condition when I replace them), HT leads, coil pack, a lamda sensor (the first after the exhaust downpipe) and a fuel pump and filter.

I've got a 2009 Tiguan with 65k miles on it. A few weeks ago I noticed some issues with running rough during a cold start. I only noticed because the engine would vibrate considerably more than usually for the first few minutes of operation, and would idle at around 1050-1100rpm instead of the usual 750rpm. After warm up, things were fine. Suddenly the issue got bad real fast - wife was out and the MIL light came on, EPC light came on, and the car was running extremely rough. We managed to drive it home (2 miles) doing under 20 the whole time on side streets. Once I hooked it up to my OBD reader, I was seeing cylinder misfire codes on all four cylinders.. P0300, P0301..P0304, all five codes simultaneously.
Since the car was due for an oil change and hit 65k miles recently, I decided to throw new plugs in there to see if that would work. It did, at first.. A day or two it ran completely fine, no rough starts, no misfires, I thought I had solved the problem. The old plugs had some deposits on them and were original, so I thought I was in the clear. Two days later, same thing happened again.. EPC light, barely running and misfires on all four cylinders..
I read up some online and decided to order new ignition coils. Took a few days, but I got four new coils and threw them in. Again, problem solved it seemed. No more EPC light, misfire codes didn't come back and no more rough starts. I drove a good 40 miles with no problems at various speeds, but started noticing some misfires during acceleration (slightly rough acceleration, almost feels like a back and forth rocking motion, very slight). Sure enough, after a cold start I'm seeing the engine run a bit rough again with misfires. This time, only P0304 (misfire on cylinder 4) is thrown, and it only shows up as a "pending code" (engine light flashes for a few moments during start, but does not stay on).
I checked my connections, swapped the plugs and coils in what I thought were cylinders 3 and 4 (closer to the driver side), nothing. I swapped what I think are cylinder 1 and 2 (passenger side) just to be sure, but still nothing. At this point I'm pretty lost. I know enough to be dangerous with a carbureted engine, but am lacking in knowledge when it comes to a fuel injected turbo charged VW engine. It seems to be cylinder 4 misfiring consistently at this point according to the OBD reader.
Also of note.. I had some misfire problems last year, and had my intake manifold replaced as part of a recall (also had carbon deposits removed at the same time). Can a carbon build up occur this fast? Can it be the injectors?

My truck was running rough when cold, I went to check the ficm voltage while wife was cranking and coolant shot right into the ficm and cooked the sumbitch. Stop laughing that stuff happens to me all the time. Anyhow, got a new ficm and truck wont start. Starter kicks out after a few revs. I ran my own solenoid wire to the starter and it cranks just fine. ficm at 48.5 koeo and cranking, icp 1100+, ipr from 14.8 to around 40%, ...
It takes a few seconds for the cam/crank to sync but it does. I changed the fuel filters and primed it, Got new batteries, and threw a crank sensor for s+g. With the key on and me cranking it using the solenoid wire, it almost starts. But from the key it will kick out after a few seconds. All fuses and relays are good. I hear the pcm also controls the starter, could that have cooked when the ficm went or would it blow a fuse? Diagnosing using a scangauge2 ....

I have a 2001 Toyota Sienna xle that started running rough when the weather turned cold. When started, the car idles very high and will not shift properly until it was been running for around 5 minutes. After that it will run well for about 10-15 minutes and then begin to run rough or poorly. The problem is very noticeable at low speeds and when stopped. It never actually kills, but it feels like it is going to. At high speeds it is less noticeable but occasionally you will feel it jerk or chug like the transmission is slipping or a belt or something.
I took it to a mechanic who checked the codes and found that the ignition coils were supposedly bad. I say supposedly because they replace three of the ignition coils and the problem still persists. I then took it back to the mechanic who then told me it was the oxygen sensor. The o2 sensor was replaced and the problem is still there with no noticeable improvement. I again to it back to the mechanic who tells me that they scratching their heads.
I have done some looking around on the internet and have found some discussions that seem to have some promising leeds and actually last weeks car talk show had a caller who described a similar problem. The guys told him it could be a oxygen sensor but they thought a better possibility would be EGR valve or a vacuum leak. Not sure if this sienna has an EGR, but I plan to suggest looking into it to the mechanic. Also, I found some discussions talking about the idle control valve and the engine control module.

When I first start my excursion in the morning, it starts fine, idles fine. If I don't let it sit for about 5mins plus i have this issue. I will start off and it has no power at all. I can barely get up to 20mph. It doesn't seem to want to change gears, I don't hear the turbo spool up. Then all of a sudden it will go to next gear, turbo spools up and it has power again. It is like I said a 6.0 power stroke, its a 2004 excursion with 214k miles.

I had been fighting some problems with injectors for several years. I didn't have time to dig into it. I knew what I needed to do, just needed to find time to do it. I honestly thought it was and injector and thought I would have to go to new sticks because I've had so many problems with the remans.
Well I finally had time last week. I pulled the passenger side valve cover and ohmed the injectors. It would be almost impossible to get the leads in the injector while installed the truck. I kept an old valve cover harness, so I cut a pig tail off of it and plugged it into the injectors so I could test. You can see the meter attached to the pigtail in the pic.
To my surprise all four were all right around 2.7 ohms. You need to set your meter so you are getting a reading w a decimal. If you set it to high it will only show a whole number and it is better to have a more accurate reading.
I then plugged the wiring harness back in and tested it from there. The #7 injector gave over 6 ohms. This told me that my wiring harness was bad. I went OE and replaced it. I had a problem w a Dormant valve cover gasket before so didn't want to go that route. After I replaced the gasket and harness all my readings were under 3 ohms. They were all lower than w the old harness.

So,I am working on a 2003 F250 6.0 manual trans. all stock. 204,000 miles. I got it not running. Charged the batteries and pulled the 14 codes accumulated by the last people trying to work on it.There were cyl 1,2,5,6,7,8 contrib codes, P0403 and P0405 egr(the egr was unplugged when I got it), P0341 Cam pos., P0500 VSS, P0562 voltage low, P0683 glow plugs, P1378 fuel inj. ctrl., and a P1000. It is on it's second used car lot, no one can fix it and I don't know what they have done.
Cleared the codes, removed, cleaned, replaced the EGR, installed new batteries, and went over the wiring harnesses. I am down to the P1000, an occasional P0405, and random cyl 3, sometimes 2 contrib codes. If I warm it up and clear the codes, I don't get any contrib codes.
I hooked up the Scan Gauge and the ICP is 554-up cranking, starts without any long crank, runs at 644 at an idle, revs up and reads 2404 max. This is sitting in the garage.
The IPR was 14.8 to start off with, running mostly between 29.7 and 38. revving it up. The FMD is steady 48.0. I have run the buzz test both warm and cold- sounds good, no faults found. Have run the KOER and KOEO demand tests, no faults. There is no smoking. I have changed the fuel filters. I have not located an adapter to hook up my fuel pressure gauge.
As it is right now, it starts reasonably well (it's in the 20's here at night). It runs rough until the temp gauge gets to the top of the little thermometer symbol, then it runs better. The turbo sounds like it's operating as expected, nothing weird. Cold it has a rough idle and poor throttle response. Warm it idles well, with an intermittent light "shudder" .
The weirdest thing I find is the fuel pedal, when I rev it up warm, it won't come back to idle right away, takes 10-20 seconds. It also does this shifting. It does not rev up on it's own, and it will stick at any RPM. I did not find a value for TPS on my datastream on my scan tool (Auto Xray Tech scan 7000). When I let off the throttle the IPR and HPOP pressure drop. The truck was hardly driven for the last 7 years (6000 miles).
I have added some Archoil 9100, that smoothed out the warm operation even more, it drives perfectly down the road (300 miles the other day). I sent the FICM (the guys on the other forum insisted my problem sounds like the logic side of the FICM) to Ed, got it back, no change. I took a peek at the IPR, it is shiny and clean, the connector is tight and free of oil.
I removed and inspected the throttle pedal, it's seems clean and operational. It only has the cylinder contrib codes cold, and it is usually only one cylinder, that cylinder changes, first it was 8 a couple of times, then 3, then 2, now 7. Which injector could be bad and there is no smoke.
I guess the biggie here is to get the throttle to stop sticking. It runs better everyday, but the sticking could be dangerous. The rough running cold cold just be this engines normal. The light shudder at idle goes in 3-5 second increments- light shudder-smooth-light shudder-smooth...
