okay wait a min! my gt-spec headers have no o2 hook up. i never took a o2 sensor off the stock headers lol. also when i was tuned by snowman. with all my parts, the first thing he said was your a/f is perfect.... 11:1.... so im a little lost at what your saying about the o2 sensor in the headers.

 

he uses his own wideband o2 that is more accurate and that he can read. the one in the car is just for getting the car at stoich.

go look at your passenger head. there should be a wire attached just like the picture i posted.

 

dude im telling you! there is no o2 sensor connected to my GT-spec headers. are you saying its before the headers??

 

it is in the collector right before it connects to the uppipe(see the hole). just go look.

 

okay, you got me on that one. i honestly dont remember putting that thing on. i just slaped myself for this one. I was thinking your talking about the damn up pipe one. HOLLA
