Engine Performance problem
1999 Chevy Tracker 4 cyl Two Wheel Drive Automatic
THis tracker has 123K miles. My son had the car and says that it has always had a severely rough idle when in gear. The rpms drop quickly immediately after it is put in gear but comes back up to 700-900 ropm. Just seems like it is loading up more than it should compared to other 4 cyl automatics. It also idles rough but not quite as bad when in neutral or park and the A/C is turned on. It runs smooth when rpm's brought up to 12-1500.
I plan on changing the trany filter and try to check the egr valve to see if it is sticking. I cannot find much info on that egr.
Any other thoughts?
