Message	The new PTU came in a few weeks ago, but I didn't have time to put it in. Went to drive the car today and cylinder 5 was not firing. Verified with Conzult (Saw plenty of light green corrosion on the original connector.) Replaced PTU with the revised one and related wiring harness. The car felt peppier and sounded stronger, but the idle issue is still present. MAF tested good.
