Will unplugging the rear 02 sensor cause my car to go into limp mode? also any one know where i can get a new 02 sensor, since mike keeps throwingthe high volts code and it feels like it is pulling timing or something since it feels like i keep losing power but once i flash the code it seems to pull hard again?

 

Unplugging the rear sensor will not cause a limp mode.

 

alright
