Default '92 SE Intermetant stalling problem

Hello,
I have a stalling issue that the shop somehow cannot find what the issue is.

It seems to only stall when I am either not giving the engine gas or barely giving it much. As far as I recall it only happens at low speeds. eg braking for a light, turning a corner... After it stalls I can restart it right away without any other trouble. (Except when it stalls going around corners )

One thing that it now does is idles pretty rough with the engine RPM dipping then going back up. (between 500-1000 or so) Along with the RPM the oil pressure gage bounces at about the same rate.

The car does seem like it'* sometimes about to stall when I am just sitting stationary. And finally the engine seems to jump or jerk when it'* about to stall.

I'd appreciate any suggestions. It keeps me alert, but I could live without loosing my power steering while driving.

Recent Maintenance
New Spark plugs and wires @ 123,478
Replaced bad oil sending unit @ 127,434
New fuel filter @ 128,775
Current mileage: ~130,000 miles

Check for any vacuum leaks?

Vacuum leaks can cause the stalling. Stalling during turns is caused by the strainer on the fuel pump... bad design.

The fuel pressure regulator could causing the stalling also.

John...weren't baffles in the fuel tank also responsible for this stalling?

Hmm, yeah, I forgot about those because it hasn't happened to me. But of the fuel strainer is original, it'* more or less a given that it will cause a problem.

Actually, it is always on for another unrelated problem. (Cam shaft sensor I believe) When the mechanic pulled the codes though that'* the only one that was there.

The camshaft sensor and the crank sensor are both on the same circuit coming out of the ignition module. The computer checks the ignition module for timing. If you can, go to autozone and ask them for the cam and crank sensor trouble shooting printout the voltages can be read with a voltmeter to test ignition module.

Another thought on this is to check your TPS sensor voltages. You may have a dead spot in the sensor.
