hi I have a beauiful cherry red 92 firebird with 168000 miles on it. I have had it for about 5 years now, I have always taking good care of it, doing all the repair work on it myself. lately it has been stallling almost every time I come to a stop. I put it in park, since it won't start in neutral, and it starts right up, but it feels like it wants to die out, but then it runs fine till I come to a stop, I notice the rpms start to decline and I give it gas then it's fine. I have replaced the 02 sensor, the plugs, and wires, distributor cap, rotor, pvc valve, fuel filter & it still dies out when I come to a stop or slow down. When it's idleing, it feels like it's surging, rpm's going up & down. I'm thinking it's the electronic control module, but I can't figure out where it's located on the car.

Does anyone out there know so that I can take it out & put in a new one?
Thanks for your help.

I thought those were still on the passenger side, tucked up under the dash.

What engine?

what you are describing sounds like the iac (idle air control valve), or the tps (throttle position sensor):cool:

Your IAC has probably become gummed up and is getting "lazy".

I had that happen in my 305 TBI 92 Firebird and it turned out to be a 50 cent part. It was a little rubber hose inside the fuel tank that goes between the fuel pump and the metal gas line. You gotta remove the gas tank ( removing some of the rear end to do ) so you might as well replace the fuel pump while you do it. But first make sure it's not the IAC ( idle air control).

I agree with 91 bird, sounds to me just like the TPS. I believe though just incase you are curious where the computer is, not sure however I've had so many cars, I had an 89 firebird and believe it was right in the middle section underneath everything, radio and all of that stuff on the floorboard, not sure of that though.

As far as I know the computer is always on the passenger side , right above the kick panel. That's at your feet, right in front of the door. The plastic panel there, it should be right above that . Either 2 or 4 bolts holding it on . But me and my friends have been playing with these cars for years , and that is not a part I'd be replacing for those syptoms. Check your fuel pressure, if it's low , then it's either fuel pump or the little bitty rubber hose I said. Could be the TPS or IAC , but I had replaced both of those on my car , before discovering it was the 50 cent rubber hose in the tank. Also we need to know your engine and your fuel system. Are you V-6 , 305, or 350? If V-8 are you throttle body or Tuned Port ?
