here are the codes

P1105 Dual Alternator Upper Fault (Monitor)
P1106 Dual Afternator Lower Fault (Control)

truck started to run crapy a couple of days a ago....the engine runs great OTHER THAN when the torque convertor is locked and the engine is operating at 1200-1800 rpms.everything begins to shutter and shake. i give it throttle past the rpms it runs perfect. runs great at wot.

Maybe i just got some crappy fuel somewhere but i am curous what the codes are. i dont have dual alternators

it also idles slightly rough just sitting in nuetral at idle.
