Does anybody else notice there idle is at 900 rpm some times after the truck is fully warmed up. My '04 never did this, it was at 600 all the time. My '08.5 has some strange issues like that, it also has a rattle that sounds like it's coming from the intake manifold at 2000 rpm only in drive not park. Is there a valve in the manifold that could be causing this? I love my truck but these issues are getting on my nerves:crying:.
