1993 Chevrolet Lumina Q&A
1993 Chevrolet Lumina Question: car idle bounces, then when at stop sign it either stalls or it sputters.
so when im driving the car it drives good but when i get to a stop light or stop sign the car sputters and the car sounds like it wants to shut off. the rpms bounce at 500 and some time drops to 400 when at a stop. and when the the rpm gauge drops the dash lights dim a little. i replaced the IAC sensor, cleaned the throttle body, did a idle reset, put some injector cleaner in, and problem is still there. if anyone has any ideas PLEASE HELP - maika87

Check the vacuum connection port at the rear of the intake for a cracked or loose hose. - pushrod
