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.
