2000 Cavalier 2.2L Starts, immediately dies if no throttle given. UNIQUE problem
I'm trying to fix this 2000 Cavalier 2.2L. It starts fine and will continue to run great if you give it throttle. Tried new IAC motor--no change. The IAC is NOT being controlled--it sits closed when having problem(I can watch the pintle through the throttle body opening). Somewhat intermittent---I got it to work 2 times randomly and it worked until I shut-off the engine w/key and restarted..then back to the dying. NO CODES stored. TPS is great, IAT great, O2 working, not running too lean or rich, great battery voltage. Just no IAC operation! I am baffled with this. I've read every "no-start" post there is(2 hrs. worth) and none were like this.

Do Cavaliers have mass air flow meters?

Nope, they have MAP sensors--which I tested and it's working great--nice and smooth throughout it's range.
