Hey Guy's I have a 93GXE with 111k on it, lately out or knowhere it begins to shake like it wants to stall. this happens until you drive it and then it stops for awhile. It happens after start up and almost every time I resart it.but not until I shut it off and start again. I changed the fuel filter but a day later the same thing.
It happens in park or in gear (auto). I tuned it 10k ago. NGK Iridiums, NGK wires
Bosch cap+Rotor, PCV. It has, until now, ran mint.

Anybody have a similar problem with their car? Any help would be appreciated.

check your fuel presuure and your injectors

How can I check the injectors? The fuel pump pressure can be checked with a gauge to the fuel line if Im not mistaken...

Do you think maybe the o2 sensor is crapping out? Thanks

id say try injectors, check all the spark wiring and even pull the plugs and check those. is it a 5spd or auto?

resistance check is the first injector check.
Fuel pressure is measured with a gauge , don't recall if there's a schrader valve on the line/rail or not.

O2s crap out infrequently , unless contaminaited by a foreign substance (ie antifreeze. the wrong silicone, oil, too much raw fuel etc)
