Troubleshooting my car! help make it run!
Tell me you blocked off the exhaust crossover ports on the intake manifold, please. 92 premium is packing more ethanol in it and ethanol will turn to gas and vaporlock your fuel line very quickly with a hot engine. And like deadly dart said the pickup coil (reluctor) will sometimes crap out when hot then work fine cold, ask me how I know.
