okay, i have a few questions, i have got a 5.0 pretty well built up, gt40p heads, and many other performance accesories, i recently put the stock intake back on because it was starving it for fuel, didnt have money for injectors, but anyways it was still popping in the intake so i unhooked the maf and it ran fine, rough idle, but it ran, so i bought a new one and it did the same thing, unhook it and its fine, dont know whats going on with that, and also the car is not over heating, but the headers are glowing red, i had the same prob with the v6 and it was idle air control valve, any ideas, on whats going on with the 2, need help and need it NOW, thanks....
