should have been 5000 miles, I'm checking on a smoke test to check for vacuum leak. Seems you can't do it with spray as the PCM will try to compensate it.
I don't know the system well enough to understand why unplugging the MAF would fix the problem. - Sdd
I think your right on with the vacuum leak. I changed the TPS and drove for 40 minutes and no problem. I did get a rich burn code, cleared it and it did not come back. Will replace problem PCV hose on back of intake and drive again. Hope this is the vacuum problem. - Sdd
