like title says, intermittent power loss. Sometimes the car feels like a 180hp car or so, sometimes even less. no boost leaks, vacuum should all be good. recent forge DV because oem failure. spark plugs, coils, all new. yesterday no boost at all( happend once), other times i allways hear boost building up, just not enough( accourding to sound) most off the time it pulls nice like it should be. My first impression would be maf sensor or n75. no cell or dtc's. anyone had same experience?
