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?

Do you have any lights on the dash? Scan for codes? I'd say clean the throttle body, and IAC. Check the throttle cable and cruise cable and where it attaches to the throttle body for binding. Then look at the Throttle position sensor as it might be giving the PCM the wrong input.

I'll add vacuum leaks to the list, your throttle body system uses the MAP sensor as a vital part of determining fuel delivery. The O2 sensor isnt that vital for the PCM in this setup. Also maybe the MAP is faulty.

Pull the codes on the truck. There is 2 wires to jump on the connector and the check engine light will flash in specific patterns to tell u codes. I dont know which terminals to jump but gonna look them up.

Jump the top right terminal with the one to it's left with the key off. Turn it to the ON position with the jumper in place and the check engine light will flash. Tell me how it flashes. Should be a sieries of long flashes followed by short ones. Example code 12 is 1 long flash and 2 short ones.
