- Scotty, my 1993 f-150 with a 5.8 Windsor had problems with idling up and down. I replaced the IAC and air filter and now the truck idles really high upon start up, especially when warm. Could it be a vacuum leak or stuck throttle and how can I tell? Thanks!

Did you use OEM part for IAC valve? Clean the MAF sensor and throttle body.
I don’t believe I used an OEM. Should I have? Also how do you recommend I clean the throttle body and sensor?
Yes, definitely use OEM for that. Also, check out this video for cleaning the throttle body and MAF sensor: https://youtu.be/NWCKvU2FmDc
