Yes, at the dealership. All we got were P0300-0303 and P0172 (none of which were showing up on my code readers...). Everything else appeared to be working okay with the ECM.

Things are definitely beyond desperate at this point. Let's just say I never thought I'd bring any car I ever owned to a dealership.

I've come up with a few other things to check, but at this point it's just taking shots in the dark...

Did they watch the techstream data, with the engine running, to see if any of the sensor data seemed to be out of whack?

BlownXA mentioned the ring land issue in another thread. That does unfortunately seem like a possible cause.

I wonder if pulling the fuel injector and coil connectors, individually off each cylinder, would allow you to see if one cylinder is acting differently than the others.
