How do you know when you are in limp mode? What does the WOT error mean and how is it detected? The throttle position switch, if I recall, detects when the throttle is closed. Does the WOT error mean the fuel injection ECU cannot compensate for the condition it is trying to correct? Check that O2 sensor to see if it is working. I recently had a a bad running engine and it turned out the O2 sensor voltage was a steady voltage. Changed the O2 sensor and the problem still existed. Turned out there was a large vacuum leak deep down under the drivers side headlight. Fixed the vac leak and the O2 sensor voltage started to fluctuate as it should and then motor immediately came back to life.
