'94 5.7 Pinging
Engine pings even under light load. Timing OK. New plugs. Trouble code 32 (EGR valve or ECM - not very specific). Don't know if this relates as engine idle is smooth and EGR diaphram is not leaking. Can't afford a costly trip to the dealer so would appreciate any help as well as a good starting place to track down problem. Thanks, Kari
