been using these forums for a while and finally decided i need an account now that my truck is acting up. I have a 99 f150 4x4 5.4 and it stalls at idle. I have used seafoam intake cleaner with no dice i plan on pulling my iac today and cleaning it. my truck only stalls during the daytime when it's a bit warmer outside i live in florida and at night the truck can hold idle just fine. Any suggestions as to what my problem could be would be appreciated.
UPDATE: i tried to get the iac off but that coolant hose is giving me trouble but i tapped the iac and it corrected idled at the standard 700 just need to find a day to change my coolant so i can pull that hose

also how do you check to see if the iac is properly functioning?
