Golf V R32 :: Rough Idle After Cold Startup
Feb 16, 2015
If my car's been sitting - say monday morning after sitting all weekend in the garage- it runs rough for a little while. Sometimes only for a few seconds, sometimes for a little while after the idle drops. The colder the car is, the longer and worse the condition. It feels like a cylinder isn't firing.
After a particularly cold and wet spell (I had the car outside) it ran so badly it threw a code for one of the cam position sensors and #4 misfire. I replaced both of the sensors. That worked a little.
Since I was due for 80k service and saw a misfire when damp, I replaced the ignition coils along with the spark plugs. That worked a little more. But, it still does it. What else could it be if not ignition? Sticky valve? something else?

My 06 Sonata runs very rough at start up when the car is cold. It appears that it is missing on several cylinders. This last for about 15 seconds and then the car runs fine. What could be causing this problem? No check engine light.

I've been chasing a problem all summer. Began with crappy batteries dying intermittently. I replaced the batteries, FICM, finally cleaned EGR valve and replaced ICP with pigtail. The problem is still persistent. Basically a rough idle, puff of whit smoke on cold startup, rough running at around 1500 rpms( driving at 50 mph). The ICP was soaked in oil so i was confident replacing it would finally cure my issues. It actually got worse with the rough idle turning to a surging idle and quite rumbly at 50 mph speed. I guess its time to look to injector issues but i thought id check if after replacing icp/ cleaning egr. I also have a slight exhaust leak at turbo out that i can see. The clamp is not seated properly. This after turbo connection to exhaust.

Normally when cold the car would start and rest at about 1,200 maybe 1,300 for a couple minutes then go down to its normal idle point, recently when starting it when cold, it sounds and looks like it wants to do that but just goes straight to its normal idle point, its only started this a couple does ago and has me a little worried now. could there be anything wrong ?

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

My V6 3.2l runs very rough for 1-2 minutes at startup when cold i.e. the first startup of the day, or after it has not been driven for several hours. Is this normal? I understand this might be something to do with the 'anti-knocking' feature. But I only use RON 98. Also I can here something like a tappet sticking when idle all the time. Is this normal, is it just a noisy engine design? The car has only done 1800kms.

Ok, I have owned my 02 Passat with the 30V 2.8L V6 since may. I got it with 115K and now its just under 129K I had the timing belt done at Jimmy's in Provo UT at 126K and up until then the engine ran great. Since the belt was replaced <along with the water pump and such> . The car has a tendency to feel like its idling rough, and when you start it up first thing on a cold morning it sounds like the valves are rattling. It does this for a brief second then goes away until the next time you start it in the cold morning. It wont do this if its warm outside, or after you start it previously that day. So far I have replaced the plugs with Bosch Platinum 2 prong plugs, and replaced the fuel pump. I replaced the fuel pump when it dead on me without warning about 2 months ago.

On start up runs very rough, will stall if not power braked or revd a little on start up/out of the driveway.
VOLT METER STARTS GOING NUTS!!
After a mile/warm up,,, runs great. But sometimes even when its hot, it will still try to do the rough idle briefly after just a few minutes restart. Give it a few revs at that point and its good. And once in a blue moon it will do it randomly at a stop light,, out of the blue. Very rare

2013 3.5 Ecoboost. Starting the truck first thing in the morning, it idles very rough for about 30 seconds and then smoothes out. If I drop it into gear it stays rough as I back out of the driveway. Once underway it runs fine and otherwise runs/idles very smooth for the rest of the day. Doesn't appear to have any other symptoms of spark plugs/boots misfire so I'm thinking it might be something else?
On my old 02 F150 with the 5.4 this usually happened when the Idle air control (IAC) would get plugged up with carbon. I'd clean it and the idle would smooth out. This truck doesn't appear to have one.
Spark plugs are on my list for the near future. 47k on the truck so they are almost geting due. Trying to get my superduty sold before I spend a lot of time on this truck.

I have a 03 explorer 4.6 at cold start-up it wants to stall and it idles very bad just for maybe 5-6 seconds and then the idle picks up and it's fine. This only happens on cold start-ups, if I drive it and restart it's fine.
This started when I replaced the two front (up-stream) O2 sensors, I didn't need to change them just have 150,000+ mile and was trying to do something to get better mpg.
Do We should disconnect and reconnect the battery after replacing the O2 sensors on an 03? Reset the computer?

My g/f's 2004 Ford Escape (3.0L V6 AWD 112,000mi) is acting up. After a full day of sitting, with the second half of it raining steadily, she was driving her Escape and it was acting funny (miss-firing, she said). The engine light came on and soon began blinking. She got to my house shortly after it started this. We left it and I drove for the day. Later that night, I drove it and it seemed fine. The engine light was on, but not flashing anymore.
The next day I took it my friend that was a Saturn mechanic and now working at a KIA dealership (same owner as the former Saturn and current Buick/GMC and Chevy Dealer). It ran fine for me. So he tries to scan it, his Mac Tools scanner won't read it. The KIA scanner wouldn't read it. I drove it the Ford dealer up the road. They said they couldn't get to it until after lunch, I just want the codes read. They re-iterated, and I told them to pound salt and went to an independent shop where I know a guy. They read it right away for me. "Mis-fire on start-up" & "Cylinder 4 Mis-fire." were the two codes stored. He cleared them.
She got the tune up basics (plugs, wires, air filter, etc) and did the complete tune-up herself yesterday. (I was impressed). She put 94 in the tank and some fuel system cleaner in it as well. She said there's been no change and today I finally saw what it was doing. Sometimes during idling at a stop light, the RPMs will drop to almost zero, the lights dim but so far it has not stalled. It'll do this for several seconds, then correct itself and idle normally.
Currently, the engine light has not come back on. She's thinking coil pack (each cylinder has a coil on these engines) on #4. She wants to switch it out with #1 and see if the problem follows. I think that might uncover the cause, or it could be the battery. It's the original, never been replaced and has a lot of miles on it, but it survived this past winter, without trouble. In my experience, most batteries crap out due to age in the fall when the cold snaps start.

Happened last night two blocks away from home. The idle seemed a little rough at start-up but didn't think much of it because the coolant temp was only 132 degrees. Pulled out of the driveway up to the stop at the corner. Totally bogged upon accelerating, went a block, then came the sound of a hubcap rolling down the street along with a check battery light, no power steering, and REALLY sucky brakes.

1992 camry 4 cylinder ... Since having my engine replaced with a used engine block my idle speed when I first start it up or when it is cold is around 2000rpm which lasts for about 2-3 minutes until it begins to fall to the normal range of 1200-1400 and finally to 850 or 900rpm when warm. how can I fix this or is it okay to idle at 2000rpm for a couple of minutes? is it hurting anything?

I am currently working on a 97 ranger with a 4cyl and 5 speed. its having some idle issues that i cant seem to pin point, you can start it and it will idle rough then when you rev it up it chugs real hard then dies. used my scan tool and all the sensors are good, fuel pressure is good, good compression, all 8 plugs are firing good and no codes. The other deal that has me a little confused is when I unhook the hose that runs from the air intake tube to the valve cover, I get a lot of vacuum at that port on the valve cover that the hose hooks to. Also when I plug it and pull the dipstick, I get vacuum at the dipstick tube. never seen this before but at the same time I've only messed with very few of these trucks so I don't know whats normal.

What causes elevated engine idle when cold or initial startup? Asking another way, what would cause it not to have the elevated idle on start up?

So I'm nearing my wits end. I have an '11 GTI DSG, CCTA, second owner. The problem has been happening as soon as I bought it, when it was only 6 months old.
When the engine is not fully warm, but warm-ish, the engine doesn't reliably start on the first try. I have KESSY, so I push the start button and hold it. When I release it (not too soon, mind you) the engine will idle very rough. The tach will bounce between 200 and 700 rpm. Sometimes the engine will die completely. Other times, the idle will stabilize at the right engine speed after a few seconds of roughness.
It seems like this happens most often when the car has been parked for 1 to 3 hours. However, I have had it happen very rarely when cold as well as minutes after parking. But definitely it seems to happen mostly when it has been allowed to cool slightly for 1-3 hours.
I've got youtube videos. I'll post links. I've contacted VWOA. I have a case. They tested the fuel system and believe everything is okay. They told me they suspected bad gas. I religiously used Shell 93. So they, under warranty, flushed the fuel tank. Okay, so I switched to Chevron 93. Well, the problem still happens!!! As far as I know, no parts have been replaced yet.
My car is at the dealership now, they called me today and want to give up. This would be the 5th time I've taken it in for this problem.
One thing I forgot to mention. When the engine has just started and is idling roughly, if I stab the gas pedal a little, it will bring up the revs to 2-3000rpm and 90% of the time the engine will then settle into a smooth idle immediately after the revs drop. It's almost as if the mixture is so rich that it has got the plugs wet (if this were carbureted, that'd be the first thing I would suspect)

So, I had noticed copious amounts of smoke on startup a few weeks ago and took it to the dealer. They said turbo seals were bad and were going to replace. However, once they looked at it (and consulting with vw engineers) they concluded turbo was fine and that the ccv must be faulty. So, they replaced the valve and tube and returned the car to me last week.
Before I take the car back in and have them start pulling my engine apart I thought I would get input. It only smokes when cold, and doesn't appear to smoke while driving. No performance issues at all - runs awesome. Fluid levels are fine. Smoke doesn't really have a strong odor or oil or glycol.

In recent months I hear some new noises at cold start. First is coming from the front of the car, a few seconds I start reversing from a cold start, sounds like an automobile equivalent of my back cracking. Not metallic, more plastic-ish. Could this be "pad slap" from my front brakes? It happens about 75% of the time after a cold start. Second is from the rear-end but that is consistently linked to the first time I depress the break pedal once the car is in Drive, again after a cold start. Its more like a one-shot "thud" whereas the front-end noise is a bit more elongated.

My 1.8t is very rough at idle when cold, smooths out when over 1000 rpm and when at normal operating temperature. Code reader says 171 and misfires.

My 2007 6.0 has a really rough (almost 'miss') during cold start up. After 5 seconds or so, it smooths back out and sounds normal. Until gauge reaches normal operating temp - there is a surge/lack of power during light acceleration. I also hear a frequent compressor coming on and running for a while which I am contributing to a possible vacuum leak. Maintenance is always done on time and I've already had a few costly repairs (both internally as well as externally) on the engine. I usually always wait for the glow-plug indicator to turn off before cranking the engine and let it idle for 5-10 minutes prior to driving it. Once the vehicle climbs to normal temp. everything seems to be fine but the compressor still comes back on every so often.IS it worth simply replacing the vacuum canister located behind the passenger side battery - or should I find someone to hook up a diagnostic unit first?

Car has been running flawlessly up until about 3 days ago. One morning got in started up and started misfiring at idle. Didn't think much of it as it does that on cold start. Driving down the highway when I apply 5-10% light throttle the car bucks and doesn't feel smooth. WOT is fine. Pulled into a gas station to fill up and it stalled as soon as I put it in neutral. When I tried to start it back up it started for a second then stalled out again. Finally I gave it some gas while I started it up and got it to idle on its own (idled around 600 rpm, down from my usual 800 rpm).
At this point I am thinking boost/vacuum leak. I leave the gas station and get caught in traffic. Car is not overheating. All of the sudden I notice a bunch of white smoke coming from the tail pipes. I pull over pop the hood to check coolant. No leaks and bottle is full. The white smoke smells like burnt oil. finally notice a VERY small oil leak at my turbo oil feed line. I checked the oil level and it was still exactly where it needs to be.
I have my buddy at the dealership looking over it now but I am really worried that I might have blew the turbo..
