Well, what did it end up being bud? I have a similar issue, even the occational no hot start. So, please get back with us! Thanks

 

I'm am having the same issue with starting and driving cold, it will just sputter down the street, no matter how much you stomp on the petal. I also get the death wobble, almost feels like a bad u joint. This continues until it warms up then it runs pretty good, with the occasional miss. I am very interested to learn what the problem was with yours.

 

Guys with " stiction" issues. . . . . $50 fix. . .get some hot shot secret, run for about 500 miles and you should see some improvement. Keep running till next oil change and stiction will be cured. Then quality oil, ( I run a syn blend 5-40) and some rev x and you should be fine. If you still have issues it isn't stiction but you will still have a nice clean oiling system for minimal expense! Stiction is a buildup of crud on the spool valve that makes your injector fire. It is critical these components are functioning properly to maintain a good running truck!
