Also has new battery and new egr valve...seems to start after applying brakes hard if that has anything to do with it. Help....truck only has 105,000 not a daily driver....tranny shifts perfect.HELP!

New injector in cylinder 1 and 2. New coil packs. New plugs and wires. New egr valve. Still getting code of misfire on cylinder 2. Intermittent problem. Runs fine sometimes the light comes on and flashes. Injector circuit code also on cylinder 2.  At our wits end...truck has 105,000 miles on it. Not a daily driver...Help on what to look for next!
