The 1988 chevy 1500 had a adjustable kick down cable on the body. there should be 3 cables . 1 for the gas pedal and 1 for the kick down and the other is for cruise control

Sounds like your idle air control valve is going bad.  It is located on your throttle body and is held in with two screws.  Let me know if you have any other questions.  Thanks for rating my response and for using FixYa!

SOURCE: 1989 GMC 2500 5.7L - engine surges and stalls at idle. Loses power at cruising speed.

Wow you have replaced a lot of stuff. Lets go back to the Fuel pump. When you replaced it did you replace the hose between the pump and the sending unit. These are common for splitting. Have you hooked up a fuel pressure gauge to check what pressure you have? It should be real close to 13 psi and should raise to at least 18 or 19 when you pinch off the return line.

SOURCE: k2500 chevy 3/4 ton pick up. no power under load

IN your distributer under the rotor is a magnet and a pickup coil (the magnet is known as a pole piece) check your pickup coil for corrsion (green in color) and the module and also check pole piece for cracks in the magnet where the rivets hold it together. sometimes oil wicks up around the distributer shaft because of housing wear or the pieces just wear out over time.

My Camaro stalls when I press the gas


hello
please give year of car the next time you post so someone knows about whether it"s carb or fuel inj. if you have a carb then it will probable be a accillerater in the carb gone bad, poss a timming isue. if you have fuel inj then i would look at the (tps) throttle positioner sensor on the side of the air intake body, they do go out of calibration or go bad on many cars and trucks

Sounds like you have a vacuum leak. When the engine is cold the leak is there but as the engine warms up the parts start to expand thus closing the gaps and sealing the leak. I had this problem on my personal vehicle and it turned out to be lower intake gaskets.

Spray the intake with carb cleaner to find the vacuum leak. Check where the EGR mounts and the throttle body gasket sense you had both off.
