Engine Performance problem
1996 Buick Lesabre 6 cyl Front Wheel Drive Automatic 125000 miles
this is my sister's car. It's a 1996 Buick Lesabre. It surges when first started and while it is warming up. The rpms jump into the high range between 2 and 3 rpms while it is still cold. After it warms for awhile and then restarted it will stop. The manifold gaskets have been replaced, fuel injection cleaned, IAC sensor replaced, the variable speed sensor replaced, tuned up, I think some part related to the transmission was replaced and the car still does the surging. Is there something else that could be going wrong that the mechanics are missing? Sorry we cannot donate at this time. She is only working part-time and I am helping her when I can. The economy isn't great for anyone right now. Thanks Belinda
have the same problem?
