I own a 1991 Chev. Caprice with a 5.0 engine. the car has always been taken care of immaculately however, it has developed a problem.the car starts fast and idols smooth until it reaches its full operating temp. then whenever you put a load on the engine the entire ignition system cuts in and out all 8 clinders at once.the miss is random. so far to repair the problem I have replaced the ignition swich, the ignition module, the coil,the cap and rotor, all wires and spark plugs, I even replaced the distributer. all primary and secondondary ignition components have been replaced and the problem persists!.The engine timeing chain has been checked and its A-ok. All wireing harnesses check out good. No trouble codes show up.I have also replaced the T.P.S., the MAP, PVC, and checked the fuel pump changed all filters, checked the injectors all check out good! any ideas out there????
