BIL's car. I just swapped the engine/ computer/ harness. 2200 OHV. Worked great for me. Started idling poorly in traffic after driving and warming up. Sometimes.
Checked for vacuum leaks; one teeny tiny one of no consequence plugged-- was for HVAC or something.
Watched live data, 10 inches with or without that hose plugged. Seems low, so I checked out my saturn s series that also uses MAP; it reported 9.5. "They" say I should get 21 at idle. I could get 21 on the "comedown" blipping the throttle.
FWIW, KOEO shows 29.5 inches on the cavalier, 29.7 on the saturn, and 30.2 on my home weather station.
New sensors are $50+, I don't want to just throw one at the car.
Thoughts?
