my car is doing a similar thing. Took it to the mechanic and he thought it needed a valve job. He did a compression test, and the results were bad news for me:

cylinder 1: 150
cylinder 2: 150
cylinder 3: 130
cylinder 4: 128

So they start bad and only get worse!!! Oh well, I guess its JDM time!
Hope you have better luck than me

could be leaky injector, causes hestitaion from extra fuel

whats the compression suposed to be at? i changed the injectors already and cleaned the fuel rail so nothing can be clogging it.

The specs for compression are supposed to be 178psi.
Redserprise: it sounds like your mechanic may have not held open the throttle and/or your battery is weak.

you should really pull the codes off your ecu, even if you aren't getting an mil light.

I had the same probrem, my car would bog from 3 grand to about 5500. I pulled the codes on the ecu and i had a bad detonation sensor. But i replaced it, and got my power back.

how do i check the codes?

Sounds like a bad EGR. Thats was a common problem on 91 and 92's. Pull the EGR tube off of the BPT and see if it goes away. If so you need ot either clean or replace your EGR valve.
