P1133 - O2 sensor fault bank 1, sensor 1....is the code im getting...

now im told the code means im leaning out....but the car is sucking down major gas...so im guessing the motor is trying to compensate for the lean with more gas....

now my question is....Which 02 is that....im thinking the one on the header

How do you know the O2 wouldn't cause this? It controls how much fuel is added to the engine in closed loop operation, if it's shot, you're fuel levels will be way out of whack.


15.3 @ 89.97mph, 14's on the way?

yes it will cause that i suggest replace the sensor

so heres wat happened....i replaced my fuel pressure line a while ago when i tried to do the ho swap....then i swapped back to stock....no i checked that line earlier and sumhow a small hole got burned into it and i was loosing all my fuel pressure......so i replaced the hose and she runs like a champ.....thanx for all the advice though
