Anyone had any luck replacing coils with anything other than Motorcraft?
I replaced my 01 F150 5.4cu in with aftermarket 3 years ago and only 10k miles driven. My truck started missing and kicking and bucking while driving. I’m afraid that it’s gonna cause more issues if I don’t get this corrected soon.
Truck runs fine until it warms up then starts acting up.
Not sure it’s the coils or not, there are no codes at all. Puzzled.

 

Certain conditions are required for a code to be set, called criteria.
Among them is, the problem has to occur for a particular amount of time and a particular number of times.
If the problem does not meet these conditions a code may/will not set. You may notice something unusual and yet no codes. Not unusual.

What needs to be kept in mind, "A code doesn't always mean a defective component". It could be wiring , connections, or something leading up to the condition and this is why some problems can be difficult to pin down. The code is to provide direction of the system involved and the rest is up to the tech to determine the root cause. They haven't invented a machine yet that tells you exactly what is wrong and how to fix it. Some may claim that theirs does, but then why do we need experienced technicians/mechanics?

 

Hanky, thank you. I’m assuming it’s a or the coils again and ordered a set from RockAuto. Should be here by Friday.
