Stalling

Any help on this would be greatly appreciated. This is regarding a 90 formula with 5 speed TPI, stock no mods. The problem is constant stalling when it's in gear and warmed up, the oil pressure drops, and the check engine light comes on. In nuetral and at WOT the car is fine. Any suggestions? BTW the car has been sitting for 6 months, I put fresh gas along with some fuel sysetem treatment in.

Did the fuel filter, no change. However, the next day started it up and now it really runs like crap, hot, cold, all the time. the thing had recent plugs and wires installed, and none of the wires are loose. If I hadda guess now, I would say the injectors or ecm? I'm gonna scan for codes tomorrow.
