Default weird idle when cold

Ok what the hell... When i start my truck (cold) its got sort of a rough idle. Sort of a faint pulsating rhythm. Then once its warned up, it idles smooth! Like even when i start off driving when its cold, it accelerates sort of.sloppy. Like the sensation.of on gas off gas on gas off gas. Only for like 1 minute. Could it be because of my SYSTEM TOO LEAN code? Thanks.

Mine is doing something similer. I also have a 3.0 v6. and when i start it up u can hear the RPM's fluxuating. Its only gotten worse. I have no idea where to evens start. Mine stays rough for a couple minutes until running a bit. but its not only when cold. I could have driving a while turned it off left for 10 min and came back and it does it again, but less. (( I cant believe there has been no other comments on this thread...

Get your codes pulled and see what the computer(s) say. I had this issue, which turned out to be a #6 misfire caused by the PCV elbow being pinched shut. Replaced that, and viola...instant smooth idle again.

Pull the idle air control valve and spray it out with throttle body cleaner, let it dry and put it back on. Worked for me as it was all full of carbon buildup, probably use most of a can of cleaner and a few q-tips will get the job done. NOTE** not carb and choke cleaner.
