knocked the ECT connector wires loose?
so my guess you mean, hot engine races,because cold engines all do that , by design.
racing idle hot.
- engine not hot. thermostat bad.
- engine hot and Ect Sensor lies, (wires fell off)
- ISC valve stuck open or wires, bad to it.
- vacuum hose knocked loose or you cracked it, now sucks air and engine races, (speed density EFI systems
- .
lots more, but am lazy , on beach
