I had a hose leak on my spark plug & coil,it was a real pain to find out why I was running like crap.The leak was very small and hard to find.Anyway I changed the coil myself because they said it was not under warranty,they wanted $310.00 to repair the heater hose and coil.
My question is,is there a trick to pulling up the boot from the spark plug.I pulled it so hard that the silver clip that goes over the plug stayed on the plug and I had to change that also,another problem,I had to borrow a special tool from a friend who work's for a garage with the city who has what I needed.Now I wonder if I take my truck in for a tune up if they are going to change the coil and plugs too.
It will need it some day. Thank's

 

Ease of the next coil removal=dielectric grease.
The coils are removed at a tune up that includes plugs.
The coils are not replaced unless they go bad.

 

I haven't changed the plugs or coils in my Tranny yet.

 

The coil did go bad,because before I changed it the Truck felt like it was running out of gas.I brought it to Ford and they told me the heater hose split and water leaked on the coil.After I replaced it it ran strong,by the way when do you change your plugs.
