Awhile back I posted on here asking about my father's 2002 S10 not idling at times. It never seems to act up when anyone else is driving it. We have removed the throttle body and cleaned it, replaced the idle air control motor, cleaned the mass air flow sensor, new air filter. Is there a cheap way to do some data logging? Maybe a OBD2 to usb cable? What software would you use? Any ideas? Thanks.
