Check all your grounds. The large one that runs from under the brake master to the back of the head.... the one behind the intake manifold (It actually is the ground for the coils), the one in front below the TPS....
Check also for bad wiring on the CAS too.....
Check your TPS is within spec too. It's possible the TPS is dying.
The coils ... did you put in the same "spec" coils? 95.5 will have 3 wire coils, and the earlier cars will have the 4 wire coils like the 94's.... May make a difference.....
Dave,

any chance the MAF wiring has ever been modified? my girlfriend's 94 must have had a JR CAI on it at one point before she bought it because the MAF harness was elongated. The guy did a shitty job insulating the wires after and when it rained water could collect in the sheathing and cause a short and the car ran rough and poppy like that.

he does have the propper coils (94-95 four wire, like mine)
Maf harness i checked it out, not been manipulated with
TPS is a good possibility, inaccurate reading, etc.
all his grounds are good, we cleaned all three of them
i think he checked the CAS harness, i think he did unbundle it and saw no damagesd wires, and im pretty sure he ran a continuity test as well
im not sure if he checked the coil harness yet, i know the ground is good, we moved it over to the valve cover, not sure where it's supposed to be since my car is also on the valve cover...and yes, that is a good connection, we ground the valve cover down to make sure there is a good connection
he is getting new wires though, just in case, his have 11K on then and they look good, but not the OEM ones...so we'll see how that goes

Did the "FPR" test. not the problem.
i do need to check the TPS which is something i havent tested most of my time and effort has been aimed at the CAS and Ignition Coils
i checked the Coil Harness and im getting a HIGH reading out of the 2I wire (Black w/ white stripe) its supposed to be .5v ign on at the ECU pin and its 10.4 so this is whats leading me to believe bad connection to a ground somewhere but possibly even an ECU problem. Also at idle at the Coil harness connector im reading 11.62 at on the Ignitor wire (Black w/ white stripe)
good continuity to ALL grounds and every other wire in the Ignition coil harness is in spec as well as all the other ECU pin voltages the CAS harness wires are all in spec and good.
im going to find the test for the TPS and try to do it even though i dont have a feeler gauge to do the test with. Other then that, im going to replace my wires with high quality wires and see if i can find someone i can swap out a CAS with to see if it eliminates the problem. I guess last resort will be swapping out ECU's.

never figured it out...
im not getting the igniter signal code anymore.
i am getting a sticking o2 sensor code now.
car only runs for about 15 min or so and it will start to hesitate and surge thru the power range when it does actually pull. the check engine light will come on and the car will lose all power but not stall cant even rev the RPMs. Runs uber rich too. Unplugged the o2 harness and turned the car on tried giving it some throttle and it backfires back through the air filter? Hesitates and stumbles to even rev up.
