Default Nevermind

Nevermind, I figured it out. The ECU is fine. They broke the connector in the middle of the vacuum line that runs from the engine to the front of the car and created a giant vacuum leak. If I plug the tube, the engine runs just fine.

Looks like an easy fix, just have to wait for the new parts to come in.

Just a quick follow-up. I talked to the manager of the body shop and sent him the pictures he requested. He called me this afternoon to let me know the replacement hose arrived at the shop and asked when I wanted to bring the car in for them to install the part. I asked if I could just pick up the hose and install it myself (due to the hassle of loading the car on the trailer and hauling it down there and back), which he was fine with, so I picked it up this afternoon and will install it soon.

So, very pleasantly surprised and happy with how this turned out.

You didn't mention you also didn't have brakes. Always a good clue.

Faulty ECU = bad brakes?? Seems a stretch!

No vacuum from engine to brake booster (that's what the fat vacuum line connects together) = no/hard brakes (plus poorly running engine from the resulting loss of vacuum). You can also get extra oil ingestion that can be misdiagnosed as a bad AOS.

Did have brakes, just took a little more force than usual (didn't drive it much, just to and from the trailer). However, the brakes were the big clue that led me to look at the vacuum line.

The initial post was immediately after getting it home and guessing at what I might need for testing. The edit was the next day, after I had a chance to sleep on it, process all the data and actually get under the car.

Fortunately, the body shop manager was present when I started the car to drive it to the trailer, and he heard how poorly it was running. So, there was no question as to where the issue started.
