Vacuum lines seem to be fine upon visual inspection. I've got two theories from doing research I'd like your opinion on. New MAF from Standard Motor Products not being completely compatible, but I'm doubting this because it's not throwing any codes for the MAF. Or a bad EGR Valve? Not sure how you test that though. Some symptoms that may help be more specific. When it acts worse it seems to be minorly dimming the lights after idle revs. There is what looks like something leaking onto the engine on the driver side, below the intake and EGR closer to the driver than the front bumper. There is also something leaving a very small drip where I leave the car overnight. Any opinions?
