Please help! 06 f150 5.4 miss fire
I have a 2006 f150 with the 5.4L. It is miss firing in cylinders 2 and 6. I was driving home from work and the truck started shaking any time the rpms went under 1900. It shakes really bad now. It first started with just 6 so I changed the spark plug, coil on plug, and fuel injector. Now it is throwing four different codes one for #6 and #2. One for a miss fire on the first 1000 revs and a fuel one. Had my buddy hook up his hp tuner to get the codes. We are both stumped on what to do. I am going to test the compression on Friday but need some new ideas. Please anything would help. I all so changed the plugs back in April. Thanks.

Whenever you have misfires on one cylinder or two you should always change all the plugs and cobs at the same time. I would also put some "Seafoam" in the fuel to help clear any injectors clogging up. Good luck
