Ok I had to change my water pump so I decided to change my timing belt and islets and tensioner once I got it back together and started it I had a miss so I hooked up my code reader and it said I had multiple missives code and two bad coils so I replaced them and zeroed the computer then took it for a drive and two more coil codes popped up so I replaced them took it for another ride and engine light came on again and this is the codes I got 1305/1310/1320/1340/ and po 303 bad coil pack this coil is one I just replaced I am really at a standstill the truck starts fine and isles fine you can drive it but it clearly has a miss. Oh and those 4 codes 1305/1340 come on as soon as you start the truck after they are cleared thanks

For some idiotic reason if you don't use factory coils these misfires will come up and not work the truck right. I have no idea why this h appens. The 1300 series codes are ignitor not working which leads to a pcm problem but may be from the coils not working right. If you change to factory coils then have a pro look at this because you don't want to be changing pcm as it has to be programmed to your vehicle anyhow
