KA, Knock sensor problem?

[blackrms13]

I have a stock 95 OBD-I KA in my s13 with supposedly about 80k miles

the engine at random times will have
-rough idle + "thomping" noise/vibration
-holding idle at about 1500 rpm + misfires
-possibly running rich(smells really bad)
-code 34 stored in the ECU, but no CEL

sometimes it will run VERY smooth like nothing is wrong what so ever, sometimes it will run VERY shitty...

i dont really feel any power-loss at all...so yeah

someone suggested its the Knock Sensor sub-harness thats not sending good signal to the ECU, and thus pulling the timing and what not causing this problem

any ideas?

i think i solved the problem by replacing the KS....case closed
