You need to do a compression test on bank 1 and a leakdown test on all cylinders ..** # 1.2.3.4 ** ( bank 1 , the right side as you were sitting in the car ) . You need to know if the engine is mechanically ok before you mess with the software.

compression specs are : new engine 191- 140 psi
...............................     old engine 160- 105 psi
............... allowed cylinder differance  ......44 psi
............... ..min compresion allowed.......103 psi

leakdown test specs can not be over 20%.

all test done with engine cold.

This is starting to look like I need to pull the bank 1 head. I bought a leakdown tester. 5%-10% all around except for the one misfiring cylinder that showed a little over 20%. With all spark plugs removed, air pushed to the 1. cylinder rushes out of 2.and 3. cylinder spark plug holes (they must have intake valves open at 1st cylinder TDC). FML I had the heads done just a year and a half ago.

On the positive side, I found a way to enable misfire logging on this ecu. This place is truly great, not just as a source for information but as a source of inspiration also.

I'll tell You when I figure it out... So far I haven't done anything to it.
