Slow IAC valve, dirty throttle body, unmetered air leak, TPS has a bad spot in it right at the idle position.

Reasons why an engine can run right, but stall while idling: Faulty oxygen or mass airflow sensor Clogged EGR valve Bad spark plugs Idle air control valve problem Fuel delivery system problems Malfunctioning transmission

I have a 1999 Chevy Blazer, 4x4, 4.3 vortec. We have changed the coil pack, fuel filter, distributor cap and button, the crank shaft sensor, cam sensor and plug wires as well as the ignition control module. We coming to a stop sign it will stall and sometimes when just sitting still. Sometimes it will start right back up and other times it takes several tries. I also have the oxygen sensor on order and it should be here tomorrow. Fuel pressure tested perfectly. No black smoke, no smell of rotten eggs or the cat glowing red. The only code that comes up is PO420. 4 Answers
