I have a 1994 Chevy S-10 2.2 liter. I replaced the stock motor with a Jasper engine a few years ago. I have about 30K miles on the new engine. As I put more miles on the truck, I have been having problems with the idle, I have replaced the Throttle Position Sensor, Oxygen sensor and have had my mechanic diagnosis it. No luck! The idle will change at times but will never back to where it was when I replaced the engine. It sounded fine for a long time, but it is getting worst.
have the same problem?
