A knackered PF01 TPS will also cause it on an L6 or L1 ECU.

If the PF01 TPS is broken, and sending a low voltage to the ECU even though the throttle's closed, the ECU will assume you've planted your foot on the throttle because the PF01 output drops as the throttle opens. If your Idle control valve is also stuck open, maybe because it's gummed up or because of an electrical fault, there'll be enough air flowing through for the revs to rise that high.
