93 Chevy will not idle

Asked by Jun 12, 2017 at 06:23 AM about the Chevrolet C/K 1500

Question type: Maintenance & Repair

It will start right up if I give it about half throttle it
will not stay running  more than 10 to 15 seconds
but if I put it in gear and give it gas it drives fine all
the way down the highway until I let off the gas
then it's like it's choking itself out  or stalling out

sounds like the IAC of course you don't know for sure unless these things are tested


that vehicle is getting old now- it probably needs one new everything- including a new or rebuilt throttle body-

Motor trans was rebuilt 2 years ago iv put new sensors on it new TPI new joke taking a throttle body all the way apart and cleaned it real good I don't know yet older truck but it is been taking care of far as the motor and tranny wise it just started doing this not too long ago it was intermittent it come and go come and go but now it's just doing it all the time

Well I think I found the problem when you're standing at the front of the motor looking at the driver side I have the 2 injectors if I unplug the one on the driver side lifted off the terminals and Idols beautiful just don't have the power like it should going down the road because it's starved fuel I believe it's a bad injector but everybody that commented gave me advice I appreciate it y'all are wonderful that's what I'm going to experience day by putting a new injector in see if that takes care of it


I have a 94 gmc 1500 with TBI , your has injectors , guess they're many variations. good luck
