Need help guys!! i have an 05 with head gaskets and arp head studs. havent done an egr delete or oil cooler upgrade yet. just the other day i went out and the truck started really hard like the batteries were dead, and when driving to work after the truck was warmed up when i slowed down and went to get back on the throttle it bucked and jerked and would not accellerate unless i put it to the floor. Any ideas? Changed the fuel filters thinking maybe they were clogged, didnt help.
