alright guys i have had this problem for about a year now. when it is cold and wet outside my truck will sometimes stall. if im going about 30mph and let off the gas the RPMs fall and its like it cant catch itself, so it stalls. it's a weird problem. sometimes it has trouble restarting but that is rare. from what i have read it sounds like my problem is the IAC. i have replaced the TPS before so im pretty sure this is my problem. can someone please confirm this?

Thanks, Joey

 

I experienced the same problem with my IAC. It worked just fine in warm and dry weather, failed more as the humidity increased and/or temperature decreased.

A good cleaning might fix it right up. I just replaced mine because it's a PITA to get at so I'd rather only mess with it once.

thanks for the replies guys. i think i may just replace it.

 

When you replace it, I would clean the one you remove, put it back in the box so you have a spare.
