:I've seen issues where a bad coolant temp sensor prevented a car from starting warm. Also the car idling and then falling on its face when you gave it gas makes me think MAF. If you clear the codes do they come back?
Ive tested the coolant temp sensor and it ohms within spec, the harness is good too. I changed my MAF out with a good known working MAF and still the same thing. I'm running out of ideas lol its frustrating because EVERYTHING checks out good .
