i really think its a tps went out of it... it was running great like this about a week ago. 35mpg on the highway its not a missfire at all, no missfire is detected in any scanner. befor. im thinking tps or csps.

i guess i could buy a cat, But this winter i plan to

install
Cam. or roller rockers
SLP headers (already have)
3.4 pulley (already have)
180 t-stat (already have)
104's (already have an installed)
taylor wires (already have and installed)
intercooler.

I guess ill just park it till the build and drive one of my other 15 cars lol. I really think this all has to do with putting ford wheels on my car.
