Hello, I have a 1999 Jetta AEG model. I am getting P0300, p0301, p0302, p0303, p0304. Car will not idle or accellerate. I have given it a complete tune up. New oxygen sensor, new intake gaskets, fuel pressure to factory specs, injector flow rate is good (removed and bench tested), compression excellent, engine vacuum is between 40-50 psi, no vacuum leaks found as of yet, new fuel filter and pump is working good. Ignition coil is in good order. Mass air flow sensor is clean and appears to be working. Electric air pump had become unplugged and car was ran like this for a while before it was notice. I only noticed this after I started having running problems. Plugged it back in and it seems to be working. I am stuck. Any sugestions? Thank you.
