Truck kept coming close/actually stalling when starting cold so I decided to take the throttle body off and take a look. Wow was it dirty! Used some throttle body cleaner, toothbrush, and soft sos pad to clean it up. Turned out nice. Fired it up and what a difference. Was idling around 500-600rpm now closer to 700-800. Feels much better. Just got the heater T's in so I'll probably tackle that this weekend.
