Here's the deal:
Friday night the car was working fine. Rolled into the garage to fit the bucket seats, then rolled back outside, all was fine. Yesterday, rolled into the garage to finish fitting the seats, ecu light comes on, although car is still running fine! Read the codes with the trusty paper clip and get:
16 - Knock sensor,
31 - Engine rpm signal (wich I assume is because the engine was not running),
55 - ECU FAULT (this one is really scaring me),
93 - Hall effect switch.
Am going to disconnect the ecu to reset and see what happens, but anyone have any idea of what could be going on?
The car is a nova gte and the engine is a c20xe.
