Question about 1987 Chevrolet R20
I replace the distributer, the cap & rotor, spark plugs & wires, rebuilt the throttle body, TPS sensor, air control valve, EGR valve, and finally the fuel pump in the tank to get it running. now it idles at about 3000 RPM. It has the 5.7L 350 engine and an automatic transmission.
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.
