The scanner showed all sensors reading normal. we checked vacuum leaks that was good, had very good vacuum also fuel pressure is good. We just changed fuel filter. egr is good and we put a pcv valve on it roughly a year ago.

There is a idle air control sensor that would need to be pulled out and cleaned along with the throttle body, and that port the IAC Valve goes into. It is best to take the throttle body off so you can clean under neath that port. May want to replace the base gasket also, for the TBI.

I need help bad. My truck us a Chevy 1500 1995 and if I drive about 30 miles or so and hit a red light and go to hit the gas. I'll have the peddle to the floor and it will start off slow then out of no where kick in and speed up. And if I'm going down the high way and the cruise control is on and I'm going up a hill it will do that. Throttle slow then kick in and speed up. Also when I go to slow down pulling in some where the truck sounds like its about to shut off then comes back to normal. What wrong with it? 11 Answers

Ppl say it is my throttle body or my filter on my fuel pump or its I have no back pressure and my o2 senser is messed up since its straight pipe no cat converter. What is it.
