LMAO...too funny.

 

how old is the truck? when my grandpa got old they put a cathedar in him

 

 

This must be a turbo 408 thing... You are the 3rd guy with this problem, counting me

 

Really? I haven't been able to figure it out...doesn't seem like an air leak. If I shut it down and restart it right away it idles normally. Oh well.

 

Me too. I eventually gave up. It's some edge case in the idle logic, but for me it's very intermittent (seems random!). I'm at the point where changing something to try to eliminate makes the truck idle for the worse the rest of the time.

 

Sounds about the same as me. Oh well. Like you said, mine only happens once every few days.

So...after finding the leak an driving the truck around all day yesterday and letting it sit in the garage again overnight, there's no coolant on the ground. I'm confused.

 

Probably the water pump or water pump gaskets. Pretty common once they get 80k+ miles.

 

Water pump and gaskets are fairly new...probably have less than 5k miles on them.
