Well I changed my wiring harness on my 96 GSR. Afterwards i get the CEL 23. KS (Knock Sensor) defective circuit or unplugged / defective sensor. So I of course thought it might be unplugged. It isn't, it's plugged in nice and tight. So what gives????

Also, i just frigging compression tested my engine. Cylinder 2=120 and cylinder 3=90. It's burning tons of oil. How long can i drive around till i can get it fixed?
