    Thread: 2007 audi a4 2.0t FSI po300

    1. 10-08-2019 11:25 AM #1
      I have an 07 audi a4 2.0 T FSI that starting randomly wanting to almost stall out and at red lights and would clear up. Today driving home it did the same thing. Only this time the CEL flashed. After getting home a checking for codes I had po300 po301 po302 po303 po304. No other codes. Any ideas as to what would all of a sudden cause all 4 cylinders to misfire? Oh and I have noticed when driving the car for the first 5-10 miles the rpms fluctuate 2-300 rpms then levels out. Not sure if this is all tied together? Thanks in advance for any help Rob

      Random missfire's, check spark plugs than coils. Connectors for coils. Carbon build up in intake manifold.
