Question about 1999 Chevrolet Silverado 1500
Initial diagnostics showed misfiring. Replaced plugs, wires, rotor, distributor cap and coil. Had to replace injector for cyllinder #8 which fixed the misfiring, but still running really rough. Mechanics are baffled!! Any ideas? It runs roughest between 1500 & 2000 RPMs
Injectors may dirty run a pint of marvel mistery oil in a tank of ethel gas in your truck
