My 89XR7 has been acting up lately. It totally bogs down at low rpms, and then when you get to about 3K, it all of a sudden comes alive. It makes boost just fine, even reading about 8psi when I have it floored at 2K rpms and it is barely accelerating. It feels like you were just cruising, then put the gas to the floor, but it happens with the pedal kept at the same spot. I already went over the entire engine bay with some carb cleaner and fixed every vacuum leak (there were 4 or them!), one of which was the blower bypass feed line had come off, and that made it better for a few days, and now it is right back to where it was before. I also swapped out the MAF for a known good one with no change. Anybody ever have a problem like this before, or any ideas what this might be?
Oh yeah, I also was trying to figure out what this was and found my balancer falling apart, so I fixed that, but it still has the same drivability problem.
