Having problems with your 1994 GMC Sierra ?
Problems with my 94 k1500 / changed idle control valv / map sensor / throttle control sensor /plugs,wires,cap,rotor ,and fuel filter / these are all the things i have bought but nothing i have done will keep my truck idling rite when put in gear it dies when warmed up it dies checked for leaks nothing
It might be the ECU, when cold the computer raises the iddle to warm it up, when reaches temp., it dropes it down to normal iddle, but it might not know where the correct iddle is, it might be another sensor like a cam, map, throttle position senssor.
