Well I did it... I had a misfire on cylinder 3 and I decided to try and change out the coil pack to see if that would fix my problem...and it didn't.. So I decided to change the plugs. Well the stealership quoted me $475 to change them without breaking one but if they did they were going to charge me for another half hour of work which is another $50 per hole. We decided to just tough it out and do it ourselves and after 5 and 1/2 hours of work and tons of frustration here's what we ended up with.



We successfully removed the plugs from 1-4 but 5-8 were a different story... We broke 5, 7, & 8 and we broke out the lisle tool which IMHO is the best tool I've ever used.

 

I have a miss fire on#6. Parts store guy told me to spray penetration oil on them 24 hours before changing them... Does that help? I went in there to find out about lisle tool. ($60)

 

We sprayed pb blaster and carb cleaner on them and let it soak in for 30mins-1hour i can't say the difference in how it felt verses doing It without it but the amount of build up on the plugs I would have to think that it helped

 

Cool, I'll have to do that, and hope it helps. Thanks

 

I did mine with pb blaster and let them soak over night

 

Get the tool it works wonders broke the first two and then let the rest soak over night

 

happy to hear you had a somewhat easy time doing yours I am still involved with this nightmare I removed the first plug it broke I have the tool the second one also broke and I removed it but when I used the pusher it broke a piece or porcelain and fell into the cylinder needless to say the truck is in the shop and can't figure out how to get it out and don't want to touch the other 6

 

Update: after a two day run my misfire came back... I just spent the past two hours pulling the plug from cylinder 3 and that stupid pos was broke in the middle of the porcelain... I took it back to the parts store I got them from and they gave me a brand new one since they were under warranty and had to call the territory manager to give them the ok to throw in a $1.39 pack of never cease... Maybe this fixed it this time...

 

Dang man that sucks. Luckily my dad is a heavy equipment mechanic so we blew the cylinders out with his service truck

 

yah the guy I brought it to can't figure out how to get the piece out and now he refuses to do the rest of them this turned into a mess and sorry not trying to jack this thread
