When you say the TPS needs to be calibrated, how is that achieved? Right now, I have the TPS set to put out .5 volts at rest and 4.6 volts at WOT.

I'd also think about the fuel strainer. It could be either a really bad example of the notorious 92 strainer, or it came off completely. As said above, this is also a symptom of bad fuel pressure caused by a leaky fuel pressure regulator.

Judging by what you guys are saying, what would be a good way to test for the problem, since the car has to be moving?

Last night, it became evident that the car is stalling just after a turn... does that point to the fuel pump?

Out of curiosity, how much gas was in the car when it was stalling?

That'* a good question, but I suspect you have 2 seperate problems. Your fuel strainer on the fuel pump may be one of them.

I had her(it'* my girl'* car) fill the tank. It stil stalls while full. She says now it'* narrowed down to either stalling right after a turn or on a hill.

I did notice the gas gauge fluctuates a lot in this car too.

There are a couple known issues on the 92'* in the fuel tank. One is the strainer and I believe the baffles were also another issue.

I think the baffle issue is causing part of the fuel sloshing and problems on corners/hills you are experiencing.

Well, it was stalling out really bad tonight, so I tested the codes... Now I have 5 codes instead of 2....
Here they are:
21-Throttle position sensor voltage high
22-Throttle position sensor voltage low
44-Oxygen sensor lean exhaust indicated
65-Cruise servo position sensor circuit open/grounded
68-Cruise system problem (sps indicated high)

Any new ideas guys?
