Ok here is the latest on this car. After moving the 02 sensors like I described in am earlier post on the turbo manifold the car ran excellent. Still on factory tune. I put 250 miles on the car with slight boosting at 4psi. All was well and had no issues at all. Until yesterday when I drove it into work just a few miles from home at 430am car drove perfect to work I did not boost at all. No free way even, I work on a base and did not go over 40mph. I parked the car and it was idling perfectly with good afr and good vacuum. I went out to the car at lunch y6 hrs after i parked it and it was difficult to start and when it did only idled at 300rpm with no throttle response whatsoever. Vacuum went way low the best its gotten is -4.5hg now. Afr are way rich at first 11-12. Then falls off to 17. Which tells me the computer is seeing something it doesn't like. I am completely lost what happened to it while it was parked? good fuel pressure and spark. Any ideas? It sure is getting frustrating. 250 miles in almost a yr is all I've been able to put on this car.. And I'm to the point of maybe a new ge motor. But I am not sure that would even take care of this issue. it was running flawless until I came out for lunch.

Problem resolved it is back to running great again.
Some how my cam gear bolt came loose and the cam slid just enough to retard the timing like crazy. I know the bolts were torqued to spec but this time I put some loctite on both of them and over torqued by 5 ft pounds. All is great now!
