[QUOTE="meosborn, post: 1076370, member: 19"] wmadoty, I'm pretty sure that's what I'm looking for. This forum has been very adept at the head smack over the years so I figured I would give it a shot. As far as a skipped tooth, I did consider that after reading about it in other threads so I checked the timing using a timing light and it checked out just fine. That check along with the fact that it runs just fine at speed leads me to believe that I'm not looking at a skipped tooth issue. I haven't pulled that valve cover again to check the cam marks but I didn't feel I had a good reason to do so. If I did skip a tooth would the timing still be right and could it run well at speed? If the cam did skip a tooth then the valves would be open at the wrong times and that would pretty much explain the vacuum issue. Uggh, I hate pulling that valve cover. ionbeam, the TPS checks out fine. That was actually the first thing I was looking at since the off idle stumble seems to be the hallmark of a bad TPS. Mine was replaced under the recall but it was a number of years ago. Everything checked out in the diAG mode and using the multimeter. That was got me started checking the other diAG functions which lead me to the IPS. [/QUOTE]
