To be clear, I cleared the CEL before I coded the first time around. Is that true, if it pops up again and have to run the drive cycle again? I coded out following the first post, but have not completed ~50 miles to see if I get a CEL again. I'm getting more ready monitors than I have in the past so far.

Well I drove about 50 miles today, and using the OBD2 reader, all status are now "Ready", but I threw a CEL. I def coded some stuff out. I'm going to use additional site provided for diagnostics:

The shop I brought it to in the past said they had that issue as well where coding isn’t sticking. They said I should buy a used ecu to clone…thoughts? Is there something I’m doing wrong?

Very odd, last night I tried it about 5x. It showed that it stuck at one point. I cycled the engine/accessory and CEL was still present. I gave up after about an hour, and this morning I was going to attempt it again, I had Xentry connected and didn't even bother to look at my dash. CEL had disappeared, I ran a diag with an OBD2 scanner, and have 2 confirmed codes, but no CEL. I hope this works out...
