Hey all I have an issue Id like some input on. I have an '04 f150 5.4 that has intermittently ran a little rough lately. Today the check engine light came on and I took it to Autozone where their scanner read problems with 5 ignition coils. Could this be right? Just seems odd that 5 of them would take a dump about the same time. Or is there likely another problem? Any ideas?

 

Need more info Tex...mileage on your engine...when is the last time plugs were changed and have the COP's ever been changed...do you remember the DTC's

 

I just had 2 coils go bad and had 4 misfires going on.

 

Only had the truck a little over a year and yes it normally sounds like a diesel. Haha. Mileage is 136000. Unknown plug or coil change. Trouble codes were:
P0352 - Ignition coil B primary/secondary circuit
P0353 - Ignition coil C etc
P0354 - Ignition coil D etc
P0355 - Ignition coil E etc
P0357 - Ignition coil G etc
thanks for your fast responses by the way. Just don't want to spend the money and time driving myself nuts if y'all think it's the ECM or something similar

 

Change plugs with motorcraft and coilpacks
