so i bought a 1997 gst that already had a 6 bolt in it the guy lived down the street and was hurting for money so i got it pretty cheap. the car ran great until it started getting cold. if i go out and start my car for school it runs for about 5 minutes then it starts the rev up and down repeatly from about 1500 to about 2500 rpms it does not ever find a balance in rpm. it does this when the weather is cold reguardless if the engine is warmed up or not. ive replaced the iac and checked all of the vacuums numerous times and its been to 3 different shops. noone can figure it out. the car has had a few things removed such as egr and the cat. the cel is on but throws only misfires and the egr. i have spent so many hours on the computer trying to figure it out and can not. any advise would be greatly appearciated. thanks for taking time to read this i know its alot.
