Chevrolet C20 Van Just Chugging Along

Q. Hello Vincent, I am having a problem with my Van and no one seems to know what the cause is. 1991 Chevrolet 20 Conversion Van, ¾ ton, automatic transmission, carburetor, 97,700 miles. Problem: The van chugs and sputters and seems to loose speed when I give is gas to speed up, pass someone, or going up hill.

Chevrolet C20 Van Just Chugging Along

Most of the time it just does it when I give it a little gas to speed up. I have had an oil change, new oil filter, new air filter, new spark plugs, new gas filter, new fuel pump and it has not helped it at all. Do you have any ideas? I sure could use the help.


A. Try ignition system. Distributor cap, rotor, ignition wires, coil and maybe the ignition module and the pick-up coil in distributor.
