I have a '91 1LE Z28 that is an original, un-molested low miles collector car that I don't drive very often. I'm the 3rd owner of the car and it only has 37,XXX miles on it. Today I decided to get it out and take it for a drive this morning to go get some breakfast. Drove it about 14 miles to where I was going and parked it. Went in, ate breakfast and then headed back home with it. I made it about 2 miles on the trip back and the motherfucker just quit running at highway speed. (Ask me if I was mad) Anyway, did some troubleshooting when I finally got it home (had it towed) and ruled out fuel and spark...and the VATS - albeit tentatively. I can't figure out wtf is wrong with it. Has great fuel pressure, I swapped out the ign. module...checked the VATS system and it seems to be working ok. (This car has a resistor key) It'll start and run just briefly and then it just stumbles and stalls. Occasionally it will make an initial stumble and then pick back up again, but then it'll stumble again and stall. It acts just like it runs out of fuel...like the injector pulse is stopping. If the VATS was malfunctioning I would expect a security light when it stalls but this is not the case. Any of you meatheads ever run across this issue in an older GM product before? The car has an LB9 TPI 305 in it.
