Same problem, different year (1992)
I'm having exactly the same problem as you, especially when I'm going up a hill. I've checked the primary ignition signals, switched out ignition coils, tested the fuel pressure, the throttle sensor for "smoothness" or "spikes", the ignition timing is right on, the exhaust gas sensor turns on and off 5 or 6 times within 10 seconds, replaced the temperature sensor connector, looked for exhaust leaks, etc.
I haven't tested cylinder compression (I have 120K miles on this engine) and the PCV valves (mostly because I can't find the buggers...are they threaded into the valve covers?). I'm going to try pressurizing my intake system in the next few days to see if there are any substantial leaks... I also wonder about my injectors as I tried a leak-down test and they didn't hold pressure...
If you find anything out, can you drop me an email. I don't get onto this forum very often. I'll do the same for you if I get it figured out.
