Hey All,

Does anyone get a chattering noise for the first 2/3 seconds on a cold startup? My old 98 Navi did this and now my 07 does as well. It only happens if the truck sits for at least 3-4 hours OR the first startup after an oil change (does it longer the first time) and and goes away after a few seconds.

It seems to be worse in the cold/winter but not sure what it could be.
