Dyl

Started with codes p0303 and 0306 swapped coil pack in #3 with #5 nothing changed. Truck runs rough at idle and through each gear under 2000 rpm. Put new plug wires on still nothing. Light goes off and on randomly but truck almost always runs rough except for first thing in the am. Checked the light today and the code changed to cylinders 1, 2 and 3. I’ve put new cat. Converter, MAF, spark plugs and wires and a few more. Please help lol was thinking wiring but now with those 3 random cylinders we’re lost
