Things that can make it run rich will be a dirty element on the MAF sensor or a malfunction with it (no clue about these units) I have seen threads that explain how to set them. I never had that opportunity on GM cars. worse case is the cold start or another injector is leaking. unplug the cold start injector and see if it runs better. I would check for the treads on running rich and fuel injection and see if you find something that helps. sorry I can't help more.

Hey Trucker, what you have is an air flow meter which in my book does not work the same as a mass air flow sensor But similiar. It meters air flowing past the door
and has no motor moving it open or closed. Hey since the new time temp switch, is the cold start injector working now or do you still have to add fuel? |

I still have to add fuel to start it but when it is started it was running a bit rich so then I disconnected the cold start injection and it had a bit more pick up, so I think the cold start injector is stuck open. I need to take it for a good highway run to see if it is going to clean it out a bit.

I tried to start the car with the cold injection plugged in and wouldn't start, poured gas in it and it started, left the cold injection unplugged, it took off like a bat out of hell, squealed the tires, it seemed like when it warmed up it started running more crappy, wouldn't squeal the tires, sputtered, tried to floor it and hesitated and started to backfire and sputter.
