2013 5.7 with 76K. I bought the truck with 74000 on it and could find no record of it's plugs ever being changed so I decided to do it myself. Got the Mopar standard plugs and gapped the to 043. Hardest part was getting those dam plugs off of the coil packs. Drivers side was a pain. Passenger side took less than an hour. Anyways.. while the TB was exposed I cleaned the bore and butterfly best I could with TB cleaner. Put it all back together and tried to start it. Took longer to fire than usual. I think that's because of the TB cleaner that my have accumulated in the intake during TB cleaning. Once it fired, it threw a PO300 code about 10 seconds later. I shut it down then restarted it again. Fired up normally this time. Code came back after about 10 seconds. I cleared the code then took a 20 mile city driving trip. Code never came back and none are pending. Truck runs smooth and better than before. Just trying to figure out why it threw a misfire code. Any suggestions? FWIW.. the old plugs weren't as bad as I thought they would be.
