Hi, I'm new to the forum.
I bought a 97 Wrangler sport 4L manual that had a melted wiring harness by the injecters. I replaced the wiring harness and now have the following codes
P0505 - Idle Air Control
P0108 - MAP Sensor high voltage
P0320 - Ignition distributor engine speed input circuit malfunction
P0123 - Throttle Position Sensor
I have installed a new aftermarket CKP sensor.
Any advise as to what needs replacing?
