Screws on mine are stripped. Heard it’s common on this model/year. I plan on going the whole 9 yards and removing the throttle body and idle air control valve (IACV) for cleaning. When you disconnect the battery, does that mean you don’t have to reset the ECM? I’ve seen others go through a reset process where they warm up, shut off and remove some fuses, and drive again for 10 min. Overall, they said the reset process takes a full tank of driving.
