Got a check engine light around 7-8 times in the last 3 days

I get the CEL (Check Engine Light), Engine starts bucking and stumbling like how it does when theres water in the plug wires.

I hear an extremely loud clicking/tapping sound from the area of the cylinder #2 injector/fuel rail area.

Tried to get the code, but the light just stays solid (both the led on the dash and the one inside the ecu,

followed the fsm instructions, turn screw clockwise, hold for at least 2 seconds, then turn back counter clockwise,

I have done this multiple times with both the engine running and not running in key on position, still same things both leds on dash and ecu just stay solid

When I am not getting a CEL, the cars runs solid 100% for the most part, (no clicking or tapping from cly 2, injector 2) but everyone once in a while will buck/stuble very very hard just once (feels like its about to blow a rod through the block).

Im not really sure what to do since i cant diagnose the CEL, everything in the spark system is pretty much brand new (less then 1 month old - plugs, wires, rotor, cap), changed wires yesterday morning, pulled the plugs today, they look fine.

I thought about having the injectors cleaned and tested, I am less than 45 min from the injector clinic in harbor sound, and rpm diesel in ft lauderdale. Im located in Boynton Beach, FL.

Any suggestions?

I thought about taking it to the dealer, but they would prolly charge me an assload by saying I have to buy a new ecu so they can read the CEL.

Thanks

OH, Car is a 1993 KA24DE S13 Coupe, 5spd, Non ABS, OBD1
