Took truck to dealer (03 F350 6.0, 78k miles), for coolant leak and rough cold start. They fixed leak (EGR Cooler) and for the rough start they wrote "Found cylinder 2&5 eratic IC when cold. Performed TSB 7-05-04 Reprogram PCM." My question is is this the latest warming flash. Couldnt find info on this TSB. Could someone explain what this one is. Thank you. Wont know if it helped till I start it tommorow morning when its cold.
