There is a Flash available to 4.0L engine Nitro owners that address a rough idle and drop in engine speed upon gear engagement after cold start. It applies to vehicle built before Jan. 17/08. It includes 2007 up to 2008 built Nitro's.

Any numbers or tech info sheets? Wonder if it includes any other tweaks? See my post in the engine mod section.

I'm trying to get a TSB #. I will post as soon as I get more info.

Thanks for the info guys. Will have them apply it at next oil change.

Has anyone tried this yet? I'm curious, as my idle is a bit rough, but I'm not going to be the guinea pig.

Any updates to this one?
