The right bank of my motor has been running so rich after the PI swap that its charring plugs. I replaced the O2 without any luck. What would cause the passenger side bank to run rich but not affect the other side?
It was the MAF unit,I went through 2 of them till I got a good one.Do not get one from Autozone,Advance Auto,Try to get a FORD one if you can,alot better unit. I have full PI swap also,and stage 2 cams.Really? Yes it still does it. My car will actually start and idle with that thing not even plugged in then i go to plug it back in hoping the idle will be better and nothing happens. Then i go to unplug it with nothing happening again. I will most certainly check into this.
Was it the sensor for you or the actual MAF unit.
Thats weird because mine is from Advance. I needed one because when i had bought the car it had no intake or MAF. Have not had a problem untill now after the PI swap.It was the MAF unit,I went through 2 of them till I got a good one.Do not get one from Autozone,Advance Auto,Try to get a FORD one if you can,alot better unit. I have full PI swap also,and stage 2 cams.
I have had No problems in 6000 miles!!!
