Not sure what to do now

Rosco · 06-14-2008, 10:41 AM

Well i just finished reinstalling my lower and upper intake. put everything back the way it was. new plugs, rotor, cap, wires. Timing is set at 12 degrees, and the car barely runs. It's backfiring, almost dies at low speeds. but at idle it's fine. I've spent 2 days trying to figure this out and i'm at wits ends. Can anyone give me some idea's?
