stalling problem, getting bad
i drive a 94 z28, couple weeks ago my car stalled while i was stopped at a stoplight, kinda confused i started it up and went on my way. a day later i was on the highway and when i shifted into 5th gear, i pressed down on the gas and nothing happened, put the clutch down and tried again, when i came out the car shut off, started it back up and went on my way. i replaced the fuel filter and the problem seemed to stop for a few days. the problem came back and it got worse, i noticed that when it is about to stall the rpms go really low when idling, about 800, and my oil pressure drops too. Yesterday was the worse, every time i let off the gas to stop my car, the car shut off, was a hell of a drive getting home. me and my stepfather seem to think its the fuel pump, or maybe a clog in the fuel lines, but i dont want to buy the parts and go into fixing it without knowing its the sure thing.
any thing will help, thanks
