Ohm test your knock sensors and fuel injectors.
My 1992 has similar problem, though not so pronounced: It is just cold shouldered, often times backfires though intake when throttle is opened abruptly, as in accelerating from stop, or will stutter and stumble until throttle is let off and reopened, and engine RPM increases, then sometimes bucks when opening throttle at 45mph when in high gear after coasting. It really just seems lean.
I've never tested or replaced KS's. FI's are Deatschwerks retro fits, I've replaced all hoses under plenum, fuel pressure regulator, coils 2,4,6,8, tested for vacuum leaks, swapped MAF, and throttle position sensor, to no avail. Will KS's cause lean AFR?
