F150 Runs Rough in Wet Weather

weather

#1

Water somehow gets to the engine when there is wet weather (driving or sitting). Can’t locate the source. Any ideas?


#2

my f-150 would not idle without dying during or right after wet weather. it would start and then immediately die if i did not give it some gas. the culprit was the Idle Air Control Valve or IAC valve. might give that a try.
