hi, i have a 2002 f150, 2 wheel drive, 4.2 v6. threw codes p0303, p0304, and code p0316. truck idles rough and seems as it has no power when depressing gas pedal. truck has 94,000 miles on it. new ford plugs and wires 3,000 miles ago. any help would be appreciated. thanks

 

Hve you changed the coil pack? i have the same truck, it did the same thing i changed the coil pack and it runs like new again.

 

Clean the MAF it's easy and cost alot less than coil pack-at 94k it probably needs it anyway.

 

cleaned maf sensor, no better. replaced coil pack and had injectors cleaned, runs good now
