So ive been running without my o2 sensor plugged in for quite a while(harness wiring is shorted) im tired of bad Economy so i plan to rewire it and hook it up and im wondering if this may help fix my high idle.
I cant get it below 1300 rpms, tried 2 different IACV valves cleaned and set the idle for both iacv per FSM..
Just wondering if hookin it up again will have any impact, other then gas mileage
