stalling issues, getting bad

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. Today 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

Re: stalling issues, getting bad

Buy a fuel pressure gauge and check the pressure. Should be about 45 psi primed, 38 at idle, and 50 at WOT. That will tell you if it is the fuel pump right there.

I've also heard of bad EGR solenoids making cars stall when the gas is not constantly pressed down.

Fuel pressure should be 41 - 47 psi at idle with the vacuum line removed from the fuel pressure regular (simulates WOT).

in may i brought it to a mechanic. he replaced my air flow meter, intake temp sensor, and oxygen sensor. he also cleared my computer settings

it ran fine until a few weeks ago, the problems back.

im moving the someplace warmer, the car runs fine in the warm weather.
