Yes, it looks exactly like his instructions. Those are not the same instructions that came with my SC BTW. I almost remember it saying not to use the small O ring... I wish I could find them.

The code almost only comes up on long pulls at steady throttle position. This makes me think the ECU is doing a lookup, and moving a point on the long term fuel trim. It runs off the table, and sets the CEL.

I ordered intake gaskets today, I guess I have to swap them to eliminate that , since they are known to fail often on our engine.

If that doesn't do it, I'm gonna mount my EGT and wideband, and add fuel pressure till its happy.
