hey every one im new to this site and need help don't know if its already been hit on but this is my issue. if idling to warm up the car runs fine, as soon as it hits the first line it troughs a check engine light and the fan comes on, idle for about 1-2 minutes fan turns of and so does the check engine light. will driving the car shifts to third and starts cutting out and running rich with a check engine. its a 95 cavalier with the 2.2l and cant seem to link to the computer all fuses are fine and all wires from , too the ecm are good and ecm is fine just put a new one in there.did a compression check and all is good 150 140 150 140, also just replaced the temp sending unit as well. if anyone has had this issue please let me know what you found out thanks
Robert

this happend when i put my intake on..and tryed to drive my car without the mass airflow sensor or watever sensor is on the side of the intake...check that sensor and go have a auto parts store reset ur light..its guna run like crap until u do...i tryed the "relearning" thing and most of the time it works but on that it doesnt
btw on mine the fan would run really hard (u could feel it standing behind the car) and it was shifting hard..i even got it to chirp first gear on my way to the parts store..lol (had a lil fun) i also have a 97 2.2 ohv sunfire
i dont believe its got a mass air flow i think it just has a map sensor. but ill check that cause thats what its doin. and i cant get the computer to link so i cant check the codes or reset them

all fuses are fine said that in my first post, daniel cooper if i figure it out ill let you know what it was
its a 95, OBD1. unless you're scanner can read both OBD1 and OBD2 you won't be able to connect to the ECM with it.
ok kool..just figured id share wat happend from my expierience and how i solved it
