Two things here. The air plate postion sensor should be checked for voltage at pins 1&2 with the key on. There it can be graphed and scoped for inperfections. The air plate position sensor can cause this or a throttle switch. Any one thing can cause this because the system will go into limp. There is no onboard diagnostics. You have to check each sensor at a time/
