Rough idle after rain or humid
I'm new to this so we'll see how it goes. I have a 1999 ford escort that normally runs great, but after a rain or when it's humid (even when parked in a garage) it will idle rough for a minute or two and then be fine. I've only noticed it after rain or when it's humid. I've changed the fuel filter, cleaned the idle control and throttle body hoping this would help, but it rained last night (car was in garage) and with a little extra humidity...rough idle again today. Anyone have any suggestions or fixes for this? Thanks in advance - cheers!
