first of all, they are parts salesman, not techs.

a code never identifies a bad part, just a failed system.
you need a shop with a scan tool, not a code reader, to monitor the knck sensor to verify if it is working properly and the wiring needs to be checked as well.

stop with the fuses. you need a shop with a scan tool that can monitor the sensor activities. without a scan tool you are spending a lot of money on items that dont fix the car.
