Hi guys, truck is 6 litre 4x4.Battery randomly goes dead ( no phone/sat. radio or aux. equip.).It has a very slight miss at idle, stored code says excessive misfires on 2 cyl.( running mates).Comp. test ok.Changed plugs/wires/moved coils& inj./replaced inj./tried new ECU( borrowed from gm dealer)/pinned out wiring harness.Changed intake manifold gskt. Truck has 150000Km (93000mi.).Also throws random codes while driving.Converter no longer goes into lock-up since problems began.Lots of power/shifts fine.Any ideas? Multiple unrelated problems perhaps? Thanx for looking. Bob.
