Ok guys it has been quite some time since I have had time to post any updates! So after all of this time we decided to slow down and diagnose this problem step by step. What we found: lifter with a bad check valve and the timing chain was stretched out over 1/2". Once we finished replacing the lifters and timing chain, we set the timing and found that the truck was running 99% better. It still had a slight stutter and actually backfired through the exhaust. We then unplugged The timing connector, set the timing 12 degrees advanced, and took it for a test drive. It ran like a bat out of hell!!! What would cause it to run rough with the connector plugged in?? Thanks again for your help!
