95' KA24DE Sluggish and Jerks

Wassup guys,

Need some help diagnosing an issue I have. I've been searching the forums and google and still haven't been able to solve the issue.

95' KA24DE - 5 speed swapped

Acceleration is very sluggish and I have no torque at all. This car feels like a single cam honda. Also randomly during acceleration, mechanical power will cut while i still have my foot on the gas and the car will stop accelerating. Instead it will jerk. I usually have to let it jerk until it stops or throw it in neutral, wait a little bit, and then get back into gear and hope the jerking has stopped. It only happens under acceleration and its random. I've tried testing to see if I could find some type of pattern on when it occurs but it happens out of no where.

Car is OBD1 and I only have 2 CODES:
82 - Crank Shaft Position Sensor
84- Automatic Tranny to Fuel Injection Communication Line

Things I have done:
-Changed Spark Plugs
-Changed Fuel Filter
-Changed Fuel Pump
-Changed New Injectors
-Cleaned the MAF
-Compression test: 170psi across all cylinders
-Cleaned Idle Air Control Valve
-Distributor and Rotor are new
-Timing's been checked
-No Vacuum leaks..I've sprayed carb cleaner on the hoses, no change in idle
-Checked the grounds, all seem intact. I have yet to test them with an multimeter though

Things I might consider:
Knock Sensor?
TPS?
Coolant Temperature Sensor?
Change ECU? - Currently using an Automatic OBDII ECU.
Clogged cat?

Those are the only things I've come across that could possibly be the issue? Not sure if the codes the ecu are throwing would have anything to do with how the car runs? It doesn't misfire or anything.

HALP.
