Golf IV / Jetta IV :: 2003 2.0 Won't Rev Over 3k / Start And Idle Rough
I have a 2003 2.0 gas Jetta (181k miles, automatic.) that won't rev over 3k, starts rough, idles rough and wont stop setting a P0341 cam position sensor code.
The car was not running when I got it, I replaced the coil pack and it ran but not over 3k. Cleared codes, it sets the P0341 immediately.
Had timing belt, water pump, tensioner and cam pos sensor replaced. Still, sets p0341 code, starts rough, idles rough and wont rev over 3k.
The throttle servo makes a little noise when actuated, shop thinks this is my demon - suggests replace throttle body. This car is for my son who will be taking it to college soon.
Golf IV / Jetta IV :: 2003 VR6 Rough Idle On Start?
I'm having a little issue with my 03' vr6. I've had the car for almost 2 months now, which it's pretty new to me, since about the time I got it, the car would sometime roughly idle on start, just for a few seconds, maybe for 10-15 seconds, and then it'll go back to idling at 600-800 rpm and being normal.
This has happened maybe 5 times since I've owned the car, and since then I've changed the battery, and cleaned my MAF. The other day when I started my car it (the rough idle on start) lasted for maybe 30 seconds, so it kinda scared me a bit.
Also there is no check engine light. Other than the weird idle on start, the car feels responsive, quick and there doesn't seem to be lack of power. This is the only mk4 gti I've driven fast in, so there may be lack of power and I just don't know it.
Golf IV / Jetta IV :: Rough Start And Idle But No Misfires
I have an 03 vr6. I'm getting codes p0300, 0303, and 0304. I changed the plugs and the coils and still has changed nothing. In the morning when I first go to start the car it has a rough start and idles rough. But after letting it warm up it is fine. It drives perfectly fine, no misfires. None of this started happening until the car ran hot a few weeks ago. Did a compression test and everything came up fine. So would could my issue be? I'm at a loss here. I was thinking fuel issue but if it was a fuel issue, wouldn't it run rough all the time?

I have a 2002 BMW 525i with 100k miles. Since I bought it at 30,000 miles there has been a braking problem. If I am applying the brakes and hit a bump or rough pavement, the brakes start to "pulse", they make a "rattley, clattering" kind of sound, and it feels as though they will fail to stop the car. Removing my foot from the brake for a breif moment then reapplying the brake past the bump or rough pavement stops this from happening. Most mechanics claim they can't reproduce it, but I can. At about 50K miles I decided to self diagnosis the problem as a bad sensor or "motor" for the antilocking system. I had it replaced which appeared to resolve the issue for a while. But it is now back. What this may be?
View 3 RepliesGolf IV / Jetta IV :: 2000 - P1296 Code / Hard Start And Rough Idle
Having trouble with my '00 Jetta 2.0 A/T w/ 98K miles. Had the water pump replaced @ a year ago (for the 2nd time, the 1st replacement died after <15K miles.) The car has had issues with rough idle when started, especially with a cold engine, since before the 2nd water pump. I've replaced the coil pack, thermostat, and coolant temperature sensor in the recent past in addition to the water pump & timing belt.
The gas mileage sucks, and when it's idling rough it doesn't "idle up", & will stall if the gas pedal is pressed with 30 secs. of starting. Otherwise it seems to run fine. The coolant temp. sensor was replaced after a CEL indicating it was bad. The CEL went off after it was replaced, but it's now throwing a P1296 Cooling System Malfunction. I have noticed the temperature gauge fluctuates instead of staying around the "middle" since the 2nd water pump replacement, and will run "colder" in colder weather. Since spring is here, the temp. gauge stays around "normal", or the middle.
Some research online says thermostat OR coolant temperature sensor. Since the gauge registers normal now, I'm leaning towards a bad temp. sensor...?
Does the hard start/rough idle and the cooling system malfunction CEL could be related?
Golf V R32 :: Squeak Or Chirp Sound Whenever Hit A Bump Or Rough Road
Ever since i bought my .:R (3weeks ago) there has been this 'squeak' or 'chirp' sound whenever i hit a bump or rough road. Car only has 22k miles on it so this is way too early for any noises to be coming up. I've spoken to a few friends and they think it might be the bushings or my suspension was installed incorrectly. What it may be?
View 20 RepliesNissan - Sentra :: 2005 - Won't Start Easily - Rough Idle On Start Up?
I have a 2005 Nissan Sentra with 74,000 miles on it, and it has had trouble starting for 2 or 3 years. When it started, I would turn the key and the car would almost, but not quite, start, and simply turning it off and trying again would work immediately. I had the battery replaced and the spark plugs at ~50,000 miles to no avail. About a month ago, I started my car and it had a really rough idle for about 15 - 30 seconds and the check engine light came on (registered an emission issue), but it ran fine. I had to get a routine oil change and emissions test anyway and they checked the spark plugs as a first measure. They all had some wear, but one was almost worn down to nothing, which the mechanic said was a result of the spark plugs (autolites?) so they replaced them with the Nissan recommended NGK kind. The next day my car didn't start the first immediately, but on second try worked. A week later I noticed my car sometimes rumbling on idle right after start again, so they replaced the fuel filter and the fuel pump. Didn't work, I still have a rumble about 30% of the time when I start, and just two days ago the check engine light came back on (I haven't had time to get it diagnosed yet). Without knowing much about cars, it feels like the engine isn't getting enough fuel or something. Could it be dirty/clogged fuel injectors? Should I be worried that my spark plugs were worn down after just 25,000 miles?

I have a 99 silverado with the 4.8 w/186k on the clock. I am having an issue with rough idle and hesitation on cold start up. Once the truck warms up the idle and hesitation go away. I have replaced the PCV valve hoping this fixed it, but it did not. I have also cleaned the TB and the MAF.

I have a 99 lesabre cold start rough idle but smooths out . Warm no start. Trouble codes P0171, P0300, P0336. Had plennum replaced 2 years ago but I'm seeing coolant around the base of the plennum so I'm going to have to do that again but I don't think that has anything to do with the warm no start.

I've got a 2007 Cadillac CTS with the 3.6L engine. The car has begun idling rough when stopped at lights, parked, etc. A few days later, it also began starting reluctantly. The rough idle varies in intensity, but is almost always present. The CEL is not illuminated and the car seems to run fine when not idling.
A few months ago, the car began running like a lawn mower and the check engine light came on. It turned out to be a misfiring cylinder. I had all the plugs replaced along with the ignition coil for that cylinder.
The car ran great for a few months after the repair, but now this rough idle problem has appeared.
Passat (B6) :: Cold Start Delay / Rough Idle
I got the fuel pump and fuel pump control module replaced. Now I am still getting a cold start delay (5-10 seconds to start) and it has a rough idle sounding like its misfiring. This happened when i picked it up at the dealership after a new fuel pump BUT! keep in mind it has been doing this for a while so i figured it was the fuel pump.
New oem plugs and the coils were replaced when i bought the car because the coils failed during a test drive I need to scan the codes but i will post. Also this only happens during a cold start. if the car is warm and i go into target or something then start it shortly after its fine.
TSB'S I think will fix this. [URL] .....

I just imported an Toyota Belta (Yaris) 2009. When starting it after it's been siting for a while (i.e. over night) it almost always doesn't start on the first attempt, but will on the second, recording attached.
Also, it has a rough idle. Today it idled down so low when we were at a stoplight it sounded like it was going to stall.
We've changed the fuel filter, spark plugs, and cleaned the injectors and throttle body. The mechanic has run diagnostics which didn't indicate anything other than rough idle.
Chevrolet - 1500 :: 1997 - Won't Start / Idle Rough?
I have a 97 Chevy K1500 truck that i have been having problem with starting. Sometimes it will start. When it does the idle is rough. When i put in in gear it almost acts like it will shut off. Then it comes back and it drives fine. If it shut it off it may or may not start. I had the distributor cap a rotor replaced. Then I replaced the spark plugs and wires. Still does not start. It seems like it is getting too much fuel. I pulled the fuel pump relay and the truck would start then die out. When i put the relay back in truck does not start. I am not sure what might be the next piece to look at. I was thinking the MAP sensor or the throttle position sensor. So far i have not had any codes come up.

Upon start up and idle the truck has is rough, enough that it will vibrate the whole truck SLIGHTLY. Once in gear and warm, it smooths out and is fine. Unit the next stop and start.
