get to a parts stores for a code reading- report those back here

IAC- why replaced not just clean?--we are talking about the thing inside the bottem of the throttle body right?

reset the ECU by pulling the CLOCK fuse on passenger end of dash for 1 minute
that makes the system do a full reset-self test and relearn

03 have an `idle relearn` procedure required after ecu reset- ck owner book or search on here for it

 

You should take off the solenoids and clean them out. You may also try some seafoam transtune and then change your fluid.
