I put the New IAC (Idle Air Control Valve) on and it is a lot better than it was it idles at 800 to 900 consistantly but some times it still dies on me when Im coming to a stop and the rpms drop from from high to low quickly. Is there something else I need to clean or replace to eliminate that from happ.

 

If it's not throwing a code then maybe it just needs a little more time to straighten itself out.

 

i would clean the tb.
