Um, there isn't a spot for a resistor in the that board type. Just a jumper. If you have everything else installed. It is either these things. Bad burn, bad chip, bad soldering job. Do you have a constant CEL?

Re: help chipping P75

did you jumper the service connector and see a solid CEL or are you just noting that the dash CEL light is always on?

you must first check the codes...
