Anyone own a 2004-05 Ford 5.4L in F150, Expedition or Navigator? Had to have a tune-up done?
Ford has come up with a new "better idea." A lot of shops that I call on refuse to do a tune up on these vehicles - they send them back to the dealer with the nightmare of the potential problems.
What has Ford done? In these applications they are using a special shielded electrode spark plug that has a nasty habit of breaking in the head. Ford has now even designed a special tool that cuts into the broken shield and makes it so it can be removed - sometimes. The bottom line - about 10% of the time a tune-up means removing the head to get the broken parts out of the cylinder. (And if you are really lucky with a broken one on both sides, both heads.)
Anyone have access to the AllData shop data-base - check it out!
No, I don't own one. But if I did and found out about this, I would be tempted to dump the vehicle before doing a tune-up.
airjer, what are your thoughts on this?
