Hello
I have a 92 camaro rs for the last month I have had problems with my car stalling while sitting @ a light after idiling high then low & off. So we replaced the intake manifold & gasket, IAC & connectors, fuel filter, tranny, fuel injectors. Drove my car around after & it was fine then drove it to work got off the highway sat @ a light & it died. Does any1 have any ideas what else it could be.

 

Any codes??? If not my first guess after the IAC (which you replaced) would be the O/2 sensor.

 

agree flash for trouble codes. directions here Error Codes from Service Engine Light - ThirdGen.org

 

Your fuel pump could be crapping out on you. Check the fuel pressure and see if it's up to specs.
