Here it is: 1990 SC with rebuilt motor 42#/hr injectors, Stage 1 comp cam, 85MM TB, 8m MM maf, MP inlet, S ported blower, Raise SC top, KW DIC, headers and 3-2.5-3 inch exhaust. New plug wires from SCP are installed.
NOW the problem;
All three of the L spark plugs are fouled rich. The R side plugs are ok. When I put a timing light with a tach on bank 1 spark plug wires the light is constant and fast. The tack reads at double the engine speed. That is as expected. When I move it to bank 2's wires The light is intermittant but when I can get it to read constant it shows the engine RPM in agreement with the car's tach or 1/2 of bank 1. I have changed out the coil and it is the same. Ideas on where look for the problem? The coils check out on my diagnostic equipment as ok.
