[Urgent] P1391/P1393/P1316 Misfiring Barely Moves At WOT

[lincolnlocker]

Y up with a SCT "performance tune" LOL i told him to get rid of it so he's gonna buy a PHP hydra with gear head tunes after we get it running.

check the icp sensor or at least unplug it WHILE its running and see if there is a change in idle..

 

[Powerstroke Man 6.4]

So we just put in the new UVCH's and new VC's and new GPR solved 1391,1393 and put p1316 codes. Started it up let it run for 5 mins didn't drive it though. We're now changing the fuel pump. Will report back for the 5 mins it ran sounded way better.

I would've changed the GPs since you were under the VC.
