Hello all: I had posted before about an intermittent problem that I have been having with my 1993 900 Turbo 8-valve... 3 times now it has (a) started very hard, (b) ran rough until I got to my first stop sign and (c) quit when I hit the accelerator after stopping... kind of dies with a "PUH" sound and WILL NOT RESTART for awhile. I am getting spark. Okay, this stuff I've posted before. Here's the bad part: Last week I had a leak in my the fuel line from the fuel distributor to my #4 cylinder. I pulled a set off of a wreck and as they looked in significantly better condition than mine I replaced all of my fuel lines with the "new" ones. Okay, car runs smoother with fuel getting to cylinder #4, but not great. Saturday morning dawned sunny and relatively warm, so there I was out in my driveway again. I replaced my oxygen sensor as I had been having problems getting the lambda pulse ratio into the range... the adjustment screw seemed to have no effect on my mixture (or reading on my dwell meter at any rate, which hovered in the 20-to-30 degree range). Unfortunately the replacement O2 sensor made no difference whatsoever. Now the really bad part: I noticed that the car was knocking or "pinking" as you Brits say, and as it was brightly sunny outside on Saturday I happened to notice that there were AIR BUBBLES travelling from my fuel distributor to cylinder #2. Huh, I think, maybe that line has a hole in it or a blockage or something; remember I just replaced all four. So I carefully replaced the #2 fuel line with my original. Same symptoms. Every time the engine knocks corresponds to a bubble hitting the injector. My longwinded question is this: What could cause air to be introduced into my #2 fuel line. No bubbles in any other lines, and the bubbles are definitely coming out of the fuel distributor. Could a failed or failing fuel distributor account for my inability to bring my fuel mixture into range? Could it account for the car stalling and refusing to start? What can go wrong with the fuel distributor and is it internally repairable? I really don't want to replace the fuel distributor (>$500) if in fact something else may be causing these symptoms... please help. Thanks Dave
