i just purchased a sharkracing 4-2-1 header, extended my two oxygen sensors, welded a bung nut, the whole nine yards, just as the previos message board replies had said... but my engine light is still on, and its running like crap. i am very worried. i thought that the two whit wires were mixed up, but i switched them, and the problem was still there? could you guys help me, and tell me which of the white wires should connect to where, and how to fix this. (by the way the header is awesome, and before the ecu fixes itself the gains are VERY good).. thanks
