I have a 2006 Ford F150 with a 5.4 liter v8 It has started missing and sputtering when running at lower RPMs. I changed the inline fuel filter and checked the air filter. I have checked the spark plugs and wires. what else could it be. The engine warning light has flashed a few timies but never came on and stayed on

the boots on the cop's could be bad.change the boots and plugs.plugs should be changed every 60000 miles.if there is a split in the boots it can ark and send a miss fire.

The boots could be a misfire problem, but it would occur at all speeds...
