GMC 6.5 TD Rough Idle And White Smoke When Warms Up
We have a 1996 GMC Sierra 1500 Turbo Diesel and since yesterday, it's had a problem... When it warms up, it runs really rough and misses at idle. While it is doing this, white smoke spills from the exhaust. When we rev it to about 2000 rpm it runs smoothly. Sometimes at idle it misses bad enough to stall. Some say it could be the IP, EGR or injectors?
View 1 RepliesNissan - Maxima :: 1998 - Runs Rough Once It Warms Up - Doesn't Idle Well
My 98 Maxima won't idle without dying, it sputters when you accelerate, and it tries to die while coasting. I've changed two O2 sensors (AutoZone gave me the code for bank 1 sensor 1 & 2) changed spark plugs, tried fuel injector cleaner, oil change, and cleaned MAF sensor & checked the wiring. It;s still spitting out the black exhaust. Although after changing the O2 sensors it quit for about a day or two but started again (I'm guessing the other sensors need to be changed to) But the main problem is once it warms up, it really runs like crap, and is a major gas hog. I'm getting about 12 Mpg.

I bought this from my brother in better than mint condition. Always maintained. Its generating a cyl #2 misfire code.
It starts and runs like new when cold, but when it warms up, it idles rough, and generates the code. after 1500 rpm it smooths right out and runs fine.
He had it to the dealer just before I bought it and they told him needed a new engine.
I am thinking bad injector, since what seems to be happening is, when cold it gets more fuel, or when u rev it gets more fuel, but at an idle and warm, it doesn't seem to be getting enough maybe. And I see from the maintenance records, a couple of other injectors have been replaced as well.
I think the dealer got tired of replacing injectors under warranty and tried to milk him for a new engine.

View 2 RepliesGrand AM :: 2000 SE Rough Idle And Sounds Like It Might Die
I have a 2000 pontiac grand am with a 2.4 L engine it is automatic transmission. Th issue is i just bought the car from a lot thinking it was an easy fix. What happens is when i start the car it goes from a 1k idle to a 500 or lower and sounds like it might die or if i am at a stop light and decelerate too fast it also feels like its going to die and has a few times unless i keep the gas pedal pressed down. I read the codes at my local store they said it was a engine misfire, o2 sensor the front one, and the map sensor.
My farther works at a pull and save which is a lot to pull used parts from cars hes brought a used ignition coil, used boots , i bought new spark plugs and nothing was fixed there. we have replaced the maf sensor and the map sensor both with used parts neither fixed the problem. I am at my wits end here i cannot afford to take it to the shops around here and am trying to get this fixed to get back and forth to work. I may have left out parts that have been replaced, also as far as lights are concerned the check engine soon light is on .
Grand AM :: 2000 V6 SE - Rough Idle And Stalls / Gears Not Shifting When Car In Motion
My grand am has a gnarly idle issue. It stalls to turn on and once on it has a very rough idle. When I put the car into drive it stales then just turns off. Drained the heck out of my battery so I was thinking it was an alternator issue but I did a quick test and my alternator seems to be working fine. I did manage to drive my car but once in motion, gears wouldn't shift which has me leading to thinking it can be a transmission issue.

Santa Fe (CM - 2007-12) :: Idle Drops And Loss Power After Engine Warms Up
When I start the engine it works fine while the motor is cold (idle normal all smooth). When the engine the temperature reach normal operating range the car loose power and idle drops to 350-500 rpm and if i am driving I can not go over 40mi/h. I drive a 2008 Sta Fe now with 96000 KM (~~60000 miles). A month ago the engine start shaking severely and knocking noise (like some spark plugs where not working), from this to now:
Changed all sparks plugs
Changed all ignition coils
Now this situation looks more related to temperature of the engine.

!995 honda accord, 5 speed. Idle is fine until the engine warms up, then fluctuates between 1500 to 2500 rpms. The idle control valve was cleaned- no change. Valve was also replaced -also with no change. Put old valve back on. Computer was disconnected after cleaning and also after each valve change.Would the next step be to remove and clean the fast idle thermo sensor? Also how do you check the coolant lines coming in. Anything else I would need to check, clean or replace.

View 14 RepliesCelica :: Low RPM Idle At Startup When Car Warms Up
Recently when I start my car, it starts fine when it's cold because it will idle high until it warms up, but if I start it while it's warm the rpms drop to about 500 barely idlling and if I tap the gas a couple of times the problem goes away and it idles normally at about 700.
I recently also replaced the o-ring on the distributor because it was leaking oil. I reset the timing twice. It is hard to get an accurate reading in the dark, looking at a little timing mark 3 feet away, but I am sure it is at 10 BTDC.
New wires, new thermostat, air filter could be a little dirty, other than that, I am thinking it might be an oily sensor or something else?

My 90 lumina euro 3.1 has idle surge after it warms up. fluctuates between 600 and 1200 rpm when in drive. When you first get on the throttle it wants to die. Once you get past that it runs smooth while driving. Ive also notice that it tries to "buck" when its at lower rpm and barely on the throttle while pulling.
I can't seem to find any vacuum leaks, has recient tuneup, had a egr code and that has been replaced. I've cleaned the throttle body also. Previous owner had intake gaskets replaced as well as fuel injectors, fuel rail, fuel pump.
Subaru - Outback :: 2003 - Idling Rough After Warms Up / Slight Shimmy At Stoplights
Have an '03 Subaru Outback Ltd. 184k miles. Great car all in all. Has been burning 3-4 qts oil between changes every 3-4k miles. Stated idling rough after warms up [intermittently], slight 'shimmy' at stoplights. Check engine light on always, flashes at times when warms up but even then doesn't flash all the time. Took it to dealer for upcoming smog check, have a bad oxygen censor and possibly bad catalytic converter, but also said low compression no.2 cylinder--which is what I'm wondering about.
Without further diagnostics they're talking about perhaps new pistons, and/or valve job and/or short block rebuild. My questions are 1-is there any more diagnostics possible to narrow it down without pulling it apart? and 2-is it worth a rebuild or should I sell? Great car otherwise, they're talking 3-5k range for repairs, blue book on the car is 4-6k rough estimate? Been a great car all in all, aside from clutch replacement this is the first major repair issue.
