Rough Idle, Various P0300 codes
I just bought my son a 2007 F150 FX4 at an auction. I am a Disabled Vet and figured this would be a great Father/Son project. It had a very rough idea that tries to settle out at speed. I changed all the plugs and had the injectors/fuel treatment at Walmart done. Now it idles a little better (not much), but I am still getting random P0300 codes. Mostly P0303, P0304, and P0308. Any ideas on where to start trouble shooting! These engines are new to me! Thanks!

your codes are misfires on 3,4,8 need to have your coil packs checked also check to make sure the connectors have clicked it is a fairly common problem for them to not make good connection after the plugs are changed. Also the passenger side of engine is 1-4 drivers side of engine is 5-8
