So glad I found this thread--my truck is idling low and shaking badly. It actually shut off 3 times in a parking lot yesterday. Ran normal this morning.
*so far*
I've been a bad girl and not done any general maintenance on it since I bought it in '03 (except of course oil changes). I'm replacing the filter this weekend to see if this helps, as well as the air filter and spark plugs--it has 116k miles on it
