I replaced the COPs on my truck in an attempt to fix a misfire... it turned out to be the #4 spark plug. So I have 8 OEM ignition coils (COPs), all working, and all of them with brand new OEM rubber boots on them ($70 just for the boots when I got them).

Set of 8 - $100 shipped

 

still available... there has to be someone out there wanting to change COPs to fix a misfire right?

Remember... these all have brand new OEM boots.

 

truck is sold, all other parts are sold... these are the last thing I have left from the truck. someone buy them already!

 

i may be interested what year is your truck and engine size? PM ME its faster

 

Sorry... just noticed your post... PM sent.

 

bump... still available.

 

I think mine might be misfiring. When I'm at a stop light or if its just idling, the truck shakes a lot. Like, you definitely notice it. And everything is stock. Is that what yours was doing?

 

Im not sure what it would be like if a COP went out... mine was a spark plug that went out which is why i am selling these COPs cause it was a plug, not the cops.

Yours could be a misfire, but i think most people have issues with misfires when they are pressing on the gas hard or going up a hill or under load.

So i cant say what yours is for sure... any codes?

 

Oh I see. Nah, no codes. Just some rumbling.

 

Could be a low idle... might need a ecm reflash
