post head replacment

[boomer]

just had my truck back about a week from head replacement and im noticing a roll in the idle when you come to a stop. it only last for a couple seconds but sometimes if idling long enough it will do the same thing again. do you think it has anything to do with new head

mine does that. with stock head... if im thinking the same thing you are describing

I'm not sure what a roll in idle is, but I am sure I'll be listening carefully and watching for the check engine light after mine gets fixed

I had to take mine back for them to update some software. Could be that ????? Since then though they had to replace a sparkplug and a coil.

Boomer: where are you located? Any head replaced after april of 06 is the new style. I personally haven't seen any problems with the new style heads. I have seen a couple of vehicles with a slightly rough idle with no misfires though. I personally think it is due to the 600 rpm idle on a 5 cylinder engine. If the idle was even 50-75rpms more the rough idle would go away. just my two cents.
