Ok, here's what i know...I removed my DEFI HUD that was only connected to wheel speed and tach....my cel came on, and the car started stalling with the idle fluctuating between 1000 rpm down to about 300 right before it revs up again....i pulled the code and it is a P0132- O2 sensor circuit high voltage.

I have an Apex turbo timer on the car, and has been there for 3 years and never have had a problem. The timer has not worked(meaning completely unoperational) since this occurred. This is connected to the O2 circuit.

Any ideas/suggestions?

 

you need a o2 sensor
