Rough Idle

Every now and then my truck will idle rougly and some times shut off right after I turned it on. I replaced all spark plugs, thinking that was the issue, its not. What could it be? A clogged fuel filter? Recharge my K&N air filter? Anything else I should look at?

Fuel filter could be that, but i would expect problems though all rpm ranges. I would be sure to clean the IAC be sure to use electronic cleaner.

I had that rough idling for about 2-3 weeks and then my truck stopped, thought about the starter being bad, took the tranny and **** off then found out that my flywheel had 5 cracks in it and the flex plate was warn really terribly.

my truck did that once and cleaning out the IAC valve and it sorted it out. another time it was one of my o2 sensors taking a dump. another time my muffler fell off and it idled low and rough. i think my fuel filter caused that problem once also.

id say run some seafoam and clean out your throttle body and see what happens

Problem fixed. It was a simple vacuum line that was dry rotted, and just fell off.
