1996 Chevrolet S10 Q&A
1996 Chevrolet S10 Question: engine missing at low idle and take off.
Diagnosis says fuel tank pressure sensor, purge valve solenoid, mass air flow, loose vacuum could be the problem. I have changed and checked all of these plus two other sensors and no change in the problem. Please help me! What else could it be? - Visitor
I have seen where cleaning a dirty throttle bore has fixed this. The coking buildup causes turbulence to the air flow and causes stunble when accel and slight rough idle. - raiderron
