During my recent attempts at diagnosis, and previous work, I have searched - and often found multimeter readings at properly functioning sensors and components. Throttle actuator, CPS, CKS, O2, Idle Control, etc. Shouldn't we try and compile these in a reference page. I'll be happy to put anything we collectively have so far in a PDF format - with relative model/year references. I know this doesn't always prove a sensor/component is properly functioning, but it can identify one that has failed. Might save all of us from starting with the usual suspects and just throwing "cheap" part replacements at a problem. They are only cheap if we are replacing bad sensor after all, even if it is a $20 stop lamp switch. Multimeters are $15, easy to use, and dont require component removal. Good place to start with diagnosis.
