Engine Performance problem
1998 Pontiac Trans Am V8 Two Wheel Drive Automatic 90770 miles
1998 Trans Am - 2 weeks ago I took it to my local Gm dealer and for $95 dollars they hooked it up to their diagnostic machine and no troubles were found. Over this weekend I changed the oil and replaced the water pump. 3 days after doing this the service engine soon light came on. I h ave been driving the car with no issues. What are your thoughts about this.
have the same problem?
