Like the title says, my truck started idling rough this morning and threw a CEL.
Then i ran codes at Autozone and got codes of:
P0300 ->random misfire
P0301 ->Cylinder 1 misfire
P0303 ->Cylinder 3 misfire
P0305 ->Cylinder 5 misfire.
So my entire left bank of cylinders in the engine is misfiring.
I have new plugs ready, but what else could cause it?
