ok i have a nother question...i installed a bomz cold air intake and i have the maf installed with the housing and all that good stuff but my question is on the stock air box theres a 2nd plug ..theres the main plug that goes into the maf housing and then a one more about a foot or so back twards the engin...what is it?? is it part of the maf ...or do i need it even pluged in, im guessing i do cause my engin light is on or does that have to do with new intake....im banging my head on the wall on this on fellas ....

I believe your talking about the IAT. It measures air temprature. It's important because cold air is denser then warm air and it helps to maintain the correct air/fuel ratio. When it is unplugged the computer assumes it's -40ish degrees outside and adds more fuel. It won't harm the engine to unplug it but it may have a minor effect on gas milage which is minimal because of the O2 sensor will compensate. I would just drill a hole in the intake, tap it and screw it in.

The easiest way to reset it is to remove the negative battery cable. Or to save the preset on the radio unplug the pcm.
