OK, heres the deal, in chronilogical order. Friday night: car started bogging, almost stalling out of nowhere. When it was in nuetral, it was fine, but, put it in first gear, and it tried to stall again. Almost like something in the drivetrain was binding. I put the car in reverse, and the car moved and ran fine. It was late, so I parked it. Saturday: I go out in the morning to check it out. I start the car, and it started REALLY rough, almost like it was missing. Then it smootheed out and idled fine. I tried to back it up to the garage to get a better look, but it just cut off. So I pushed it back and got a look. It wouldn't even start anymore. I walked back in the house disgusted. Monday: I came home from work and once again tried to start it. It started rough again, then stalled after 20 seconds. I checked for spark, changed plugs, retarded the timing back to what I believe to be about 15(it was advanced to 17), compression tested(it checked at 150+ on all cylinders), and although I didnt' have a fuel pressure gauge, I disconnected the fuel line and seen if it had any pressure that way(ghetto fab, I know). Now I start the car after all this, and it starts right up, idles fine........for about 30 seconds. Then it just dies. It wont' start back up unless I wait about 2-3 minutes, then it will do the same thing. If I rev it, it will get to around 5000rpm, then just die again. Does anybody have any clue what the heck is going on!!??
