Stock motor.. running RICH (have searched)

Why are you running it open headers?

just wanted to ad.. i thought maybe it might be my MAP sensor.. so i took one of off of my friend's perfectly running GT
and it does the same thing..

since my exhaust is dropped, and the 02's are not plugged in.. will it make that big of a difference?

Yes!!! The o2's are what mainly control a/f mixture

when i dropped the exhaust, the factory pipes were so crappy and rusty, that the drivers side of the H-pipe fell apart basically

if i go out there and plug the 02's in, with out them being screwed into the h pipe, will THAT make any difference?
i am going to have to order full exhaust

no exhaust means no back pressure so the unburned fuel is being sucked out a little back pressure will help in fuel scavaging

No b/c there is no way for the computor to read the fuel content in the exhaust. You'll have to fix it first.

s/d cars operate different than mass air ,but yes the s/d cars do go in a safe mode for lack of o2's
