Engine Performance problem
1993 GMC Suburban V8 Four Wheel Drive Automatic 220300 miles
Guys, I had a code 22 flash when I checked the on board computer system thru the service engine soon light. I went ahead and replaced the throttle position sensor and thought that would cure my problem. As it turns out just a few days later the same code has appeared again. What else can I check to remedy the situation? It seems when the service engine light is on my performance as the truck shifts thru gears is very rough. But it does not come on everytime I start the truck and when it does not come on the truck seems to run just fine. It must have some type of default code built in if something in this area fails to preform properly.
have the same problem?
