Open loop fault. IE the O2 sensor isn't working, so the computer cannot go into closed loop mode (ie make adjustments in real time based on O2 sensor feedback for how the engine is actually running).

Not only are those wires exposed, there's corrosion which could cause many issues.

Default Egr

So i took a look at the egr. Took off and really cleaned it. Wire brush all the way through to the inside of theottle body. Is the smoke im getting after restart still all that gunk i loosened up or is bigger problem waiting?

Hard to tell without seeing the smoke. If it was just excess carbon from the cleaning making its way through, it should clear up fairly quickly. If its continuing to drag on even after driving, then I'd start getting worried.

Those readings are looking fairly normal- its good to see STFT and LTFT at reasonable levels. How does it drive? Not being sure what all you've done to it lately- what other codes are you still seeing at this point?

Now that its getting to closed loop mode (and the fueling adjustment isn't pegged), you can take it for a bit of a drive to start letting it get through all of the various emissions tests and see what parts of driving are working ok and which arent.

That thing was clogged shut. Had to use a very small screwdriver. The smoke has since went away but still getting egr code closed. Its new but was on there awhile trying to work and clogged in throttle body. Maybe burned it up ? Im gonna check the wites to it this afternoon to make sure nothing came loose. Drives ok still has what feels like a trany mount bad maybe. Vibration in car at idle.
