I have a 1978 Chevy C20 3/4 ton with a 350. When trying to turn the motor off it tries to keep running. Any opinions?
Being that year with the kind of gas they sale these days your vehicle is experiencing spark knock. Low octane gas will cause this try using the middle grade gas or add some octane booster to low octane gas.
