Check your crankshaft sensor and also give your throttle body a good cleaner, use a good cleaner such as CRC...

Need to check fuel pressure at the TBI, it needs to be 9 to 12 lbs. and to be able to hold that pressure, not bleed off. Start by replacing the fuel filter, this can cause low pressure at the TBI.

No crank sensor, no cam shaft sensor, that started 1996 with the vortec motor.

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
