Hey my car threw a P0135 (heater o2 sensor bank 1 sensor 1). Now I know this is the driverside pre-cat o2, but I had the front o2's deleted by madz28 and it is still threw this code. The car was fine for about a year after it was tuned. The car runs fine, but Im wodering if I should send it back to this dude. Also as long as the car doesnt start acting up should I be fine to drive it? Thanks

 

you sure you did not have the rear ones deleted?

 

You know what, after thinking about it. It is the rears. I was going by the tune sheet and it says front oxygen sensor delete. But I think it might have been a typo. Thanks
