I have another thread that tried to solve the problems with my car, but even with all the repairs the car still has the same problems:

- Only after car warms up (although, sometimes a little miss when cold)
- Rough idle, down to 400 and fluctuating up to 850.
- Almost stalls at idle
- Rough idle less noticeable in N or P
- Off the line, the car hesitates and jerks until at about 10 m.ph.
- Going uphill, the previous problem would be worse
- If going on a straight away and giving a slight amount of gas, the car
would "burp" and jerk, until more gas was given
- Car squeals when first turned on and in idle, until warmed up

To see all the repairs I have done see the other thread here:

Do you guys think this could be a MAF or Knock sensor problem? The car works like a champ when its cold, but once it is warm the problems start. The problems are really bad after I have been driving for a while (especially at high speeds), then I turn the car off and come back to driving before it has cooled down. I am pretty much otherwise out of ideas? Thanks for any feedback.

 

You may have to reset the curb idle after doing the throttle-body cleaning. Check here:

Also, you may want to check the TPS.

 

My car idles at 700 in D. Should I mess with the setting?
