Hey guys,
I've check the coil pack, plugs, and the spark plug wires and some of my spark plugs still aren't firing. I'm assuming either the computer or wiring harnes or both are bad. The car is a 93 LX 2.3L. Any one know any other cars with an identical wire harnes and computer set up or do I have to pull it off a 4 cylinder mustang only?

Thanks

check your distributor to the plugs that arent firing your 93 has 2 distributors the one to the plugs that arent firing could be bad wich would be easer to replace than a wiring harness

tried that already, only thing left to try is the wires and the CPU that they run to. Anyone know if i can pull them off a different car?

Does your RPM gauge work? We don't have distributors on the 1993 2.3L. Hence the term...Distributorless Ignition System. If your Tach is'nt working it might be the DIS Module. I HATE THE DIS MODULE!!! AutoZone checks those for free.
