ok when i give it some fuel when idling the whole truck rocks as it idles back down. it also sounds like it has one hell of a loping cam until it settles back down. what do yall think it is?:dunno:

How cold is it where you live? Is this also during start up? If not, have you checked your fuel filter? Codes?

could be the UVCH. pull the valve covers off and put the wedge in.

Yeah, this is a possibility, too. A few months ago, I didn't have the wedges & 1 morning before work, it was idling fine, started running rough, & then just quit. It would turn over but wouldn't start. My problem was a combo of the UVCH wedges being missing & the IDM fried. $1800 later it's running fine. :crazy:
