HELP, Rough running, no power, blue smoke

[strokr08]

i was cruisin down this backstrip and i cranked my chip to smoke setting, Dp Tuner (stock, eco, 140 smoke) as soon as i mashed on the gas my rpm's shot up like normal, then dropped, nothing popped, banged or blew out, just started to run really rough with no power at all, so i shut her off, thinking i was running out of gas becuase i was low. so went and got some gas, started it up, still very rough, no power to move truck, and some blue smoke, there is no check engine light which is surprizing, and the chip isnt overirding it becuase i took it off and it still does the same thing, i havnt schedualed a shop time yet i was just posting to pick anyones brain. lol im hoping for the best before i crack into this thing, but it doesnt look good. please help, any thoughts?

pull the valve covers off and check the connections under them that actually plug into the valve covers. Decent chance one of them is partially if not all the way disconnected. The lock tabs sag over time and heat cycles. You can replace the harnesses or ford also has a wedge that is built to prevent this from happening
