Engine Performance problem
1988 Buick Regal 6 cyl Automatic 152k miles
it use to stall or give a problem starting 3-4 times in the last 10 months. last month it began stalling after 10-15mins like it's running out of gas but the tank is full. it restarts everytime but only for a few seconds, then it stutters & stalls. i replaced the fuel filter, checked the fuel pump relay according to the manuel, checked the pump fuse, tested the ignition coils & module. a friend push in on the shrader vale while it was running between stalls & it's pushing out gas & it has spark too. 2 of my neighbors are retired car repair shop owners & they can't figure it out either. could it be the oil pressure switch? it has been leaking & the oil pressure light comes on after 15 min of driving. this was just before the serious stalling started.
