Hello folks; My 07 Nav started to miss today so figured it was time to change the plugs. The coils tested okay. # 4 and #7 spark plugs came out but the lower brass or copper ends with some porcilon stayed in the hole below the threads. Is there a way to remove them or am I pulling the heads. Vehicle has a 5.4 with 122,000 km on it and I've owned it two months. I called the original owner and he said they were original plugs. Story of my life. lol

Bert

Here's a tool for the job. Us eit carefully. Are all the other plugs replaced?

Thanks a million Bert. There has to be one avalible in the Toronto area and I will find it. The long weekend is starting so it's not going to be easy finding it. All the other plugs came out with alot of crunching noise but I think the Fluid Film spray and workng the plug back and forth helped. I have Autolite HT15 Plugs going back in. Should I put anti-sieze on them. Thanks Tony

Bert

I always put anti-sieze on the ones I do and not on the seating area, On those, I put some around the smooth tip area that gets stuck in the head. None on the tip though.

Thanks again Bert. Bought the remover kit for $90.00 and it worked really slick. Got all the plugs done. I put new pads and rotors on the front and now have the right side getting very hot. The old pads were worn and even on both sides. I leaning towards replacing the calipers. The pistons look like plastic mold type and suspect they are sticking. Tony

Bert

Raise the front and see if the brake is hanging on that side. Sometimes pushing the piston in does cause a caliper problem but very rarely. Switch the pads with the other side to see if it changes.
