i have just recently installed OBX Lt headers to my f150 screw. my full system is headers to resonators ,no cats, to two borla mufflers and then 90 out the side. tru duals. i don't have an x pipe installed bc when i got the headers put on i didn't get a chance to get an xpipe to put in.
my problem is my truck is throwing 2 CELs. one for o2 sensor heater circuit bank 2 sensor 1, and fuel/air metering malfunction code P1151. i used o2 spacers(like non-foulers) for the back o2 sensors. i would like a solution to the problem. thank you.
