greetings all,
im very uneducated on mechanics, so thanks for the help so far. my 05, f150, super crew, 5.4 4x4 started idling rough after getting cheap gas. i think idle should be about 650 rpm on gauge, but rumbles down to 500 every few seconds at a light. but will throttle up ok. so i changer the fuel filter after learning how on here, and sprayed out the MAF above throttle body{also after seeing it suggested and how to on here}, but cam across the acronym COPS, and to clean or replace them...what is that???????? and were is it, and what does it do?

thanks very much.

COP=Coil On Plug

Try cleaning your Throttle Body also.....

Also there's an issue with 2005's having bad injectors.....click link>>>https://www.f150online.com/forums/v8...ram-07m08.html

 

Actually, COP = CoilOverPlug.

If it's that critical lol.

 

I have seen both used. I think Coil On Plug is more accurate. Even Ford uses Coil On Plug:
