HELP!! Car still not fixed (87 325I)

[Tabatha]

Hi, I've spent over a thousand at the mechanics and my car is still not fixed. He just recently replaced the fuel pump, he said he drove it around for 3 days and didn't act up for him. I drove it yesterday and didn't get too far and it started acting up on me!

**The car stalls when I'm at a red light. I can start it back up and i can drive off. (My boyfriend drove it once and it stalled on him while we were actually moving. He found the best way to sit at lights is to put it in neutral so it won't stall.)

**I can put my foot on the accelerator and sometimes nothing happens and then finally it takes off. ( sometimes i put my foot on the gas and it jerks back and forward, moving but barely)

The Mechanic has replaced the Idle Motor and the Fuel Pump so far for this problem. I first brought it to him because I couldn't get the car to start and he replaced the crank positioning sensor. I brought it back to him to fix the new problem.

I don't know what else to do! I'm sick of throwing money into it when the problem is not getting solved!! I think I can at least get a thousand out of it from someone who really likes projects or doesn't mind fixing it up a little.

Have you tried replacing the fuel pressure regulator?

Do the cheap stuff first. Replace the fuel filter and put some fuel injector cleaner in the gas tank. Then check for vacuum leaks.

When you are able to drive it does it display any symptoms?
Is there any chance that you have contaminated fuel (water etc) in it?
Do these symptoms change when the car warms up?
In nuetral will it rev up and down through its normal driving rev range smoothly?
