Stuck Spark Plug
Hi all,
99 xlt 4x4 3.0 flex 86000 miles - was running fine just preventive maintenance
Tonight I changed my plug wires and only 5 of my plugs as the #1 plug is in there good. I sprayed a bit of PB penetrator on each plug, and all but the 1 came out. I have resprayed the 1 and tried a few times, but it won't budge. I'm afraid it may break.
The plugs that were in it were AGSF22PPM, but I put in the new fine wire plugs AGSF12FM after reading about the whole 3.0 plug issue. It ran fine both before and after the change.
I am driving to St Louis this weekend, about 250 miles one way. Logic tells me I need to get this plug out before the trip, but what if I can't?
Will the mix of 5 new plugs and 1 old be ok for a while? What about the difference in the heat ranges of the plugs?
What if it did break off?

Ya, I was a bit surprised that it didn't have the original plugs. The service record the dealership gave me didn't show a plug/wire change. So the previuos owner must have done it. It has been running fine today, already drove about 50 miles for work.
I know a previous post said I should be fine with the 5 new and 1 old. Anyone else have a second opinion?

I broke the tip off one last week doing a tune up. It wouldn't budge. I sprayed it with Liquid Wrench and tried about an hour later with a breaker bar, taking it real slow. It still wouldn't come out. I let it sit over night with another spray of Liquid Wrench, and said my prayers before bed (I'm serious). The next morning I got it out with the breaker bar. I have strong faith in breaker bars, liquid wrnech, and prayer.
Good Luck

Thanks for everyones input. I got home from work Friday evening, sprayed a bit more PB on it, waited about 15 minues, then while the engine was still warm, tried once more. It came right out.
So I was able to make my trip with all new plugs. It ran great the whole time (about 550 miles round trip). With the other things I did (cleaned the throttle body, new wires, etc etc.) it's running like a champ.
Thanks again guys.

Did you put some anti-seize compound on the threads of your new plugs? Really helps to prevent this type of frustration in the future. Small tube of the compound is less than a couple of dollars.
Glad you were able to resolve the problem relatively easily.
