My 97 Tahoe is hard to start. Then when it does start it will idle, but as soon as you try to give it gas it wants to stall let off and it idles just fine. I have replaced the fuel filter. Still does the same thing.

 

Throttle Position Sensor?

 

Hey thanks I will try that. Sure don't want to replace fuel pump. Only if I have to. Thank you so much this forum thing is great.
