    My car feels like its hitting fuel cut at 4500 rpm then once its past it pulls hard again. A check engine light came on and i scanned it with my AP and i got p0103 high input on my MAF. Any suggestions on where to start would be appreciated, Thanks.

    How long have you had the intake? Try cleaning the MAF and resetting the ECU.

    The intake is probably causing the problem. Reset the ECU.
