The last Test drive and fiddling introduced new codes P1128, P1130,MAF code, fuel relay. Probably due to my fuel pressure tests as I pulled the fuel pump relay and cranked the engine over to release all residual fuel pressure before doing the fuel flow and pressure tests.

I'll reset all the codes by disconnecting the battery, redo the throttle adaptation and start with a clean slate to see what materializes now that it seems to be running somewhat better.

While I was under the car I did notice some burnt oil residue on the pre Cat O2 sensors on both sides. It looks like it was from the AOS failure as it was not there prior to the event.

My car did pass about 2 quarts of oil during the AOS failure so I'm thinking it could have fouled the O2 sensors and plugged catalytic converters but I am not seeing any codes to indicate that either have failed.

The Durametric trace that I got from the O2 sensors this weekend to see what was going on made little sense as the lines were wandering everywhere.

I was looking for a sine wave on the pre cat sensors and a nearly straight line on the post cat Sensors but got a little bit of everything all mixed together.

It made me think that perhaps I was not getting enough samples per second from the Durametric to see the proper wave form.

I think I need to pull the precat sensors next to inspect them and use my inspection scope to look inside the cats to see if I can see whats going on.

The front side of the exhaust manifold cats look good, no heavy deposits.
