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!
