Car has rebuilt head on it. Got real hot from previous owner and warpped. Put new gasket on and ran before we knew this. When new gasket blew then I knew it was warpped. Put new head on it now the damned thing won't run without revin' up real high then down to hardly running and rough at that. Timing is peerfect, balance shaft is correct. Put new ECU in because we were getting low or now voltage at connectors for the sensors. I can't find a short anywere. What is the probable cause for this? Example of voltage problem is on TPS. Terminal (harness side) #1 has 12 volts, #2 has 5, #3 has 0, and #4 has zero. All suppose to have 5 volts. Totally lost here. Any help would be appreciated.
