Codes that set do not instantly clear even if the cause goes away, so it's possible you had an issue testing the TPS that set the code and when you pulled the computer is did a reset. I assume driveability is still the same?

I almost wonder if your EGR isn't leaking by causing this, similar symptoms. Can you block it off for testing purposes?

Did your vacuum readings ever stabilize?




The code reset because I removed the computer and battery. and I didn't test the TPS again after the rebuild until after I saw the code. The driveability is the same, hesitation, stalling when I come to a stop. I tried blocking off the EGR before I did the rebuild but I'll try it again. I'll check the vacuum again. I assumed it was doing that because the timing was off but I shouldn't assume. I'll check it again right now.
