So I’ve been getting horrible gas mileage out of my s14 KA for a while now.  
I checked the ECU and I’m getting knock sensor code and evap codes. I checked  
the old knock sensor, verified that is was bad, and replaced it with brand new OEM  
part. The code didn’t go away though.

During the repair I broke one of the plastic harness crimps and had to solder the wires  
directly - could this be why it isn’t working?

I’m not sure what else to do as I can’t get new plastic connectors without buying a  
whole new harness…

Any advice on this?

Same thing happened to mine, mind you it was an s13 KADE.

I changed the distributer and re-timed it and it was good to go
