When blower motor is on, it wont idle good when im stopped. It seems to search for idle speed. Goes below 500 then up to 700-800, then back down and stalls. Any ideas on what s going on?

Try cleaning throttle plate and iac on both sides with choke cleaner first. Clean iac hole as well then clean your battery terminal ends.
