Stuck Plug Wires

Any ideas for removing stuck plug wires on an '02 PA with 158,000 miles? I haven't changed the plugs before and I bought it with about 105,000. I think the plugs may be the original plugs. They are AC 41-921's and are fairly rusty. Got the 3 out on the front, but the rear are a problem. I am also changing the plug wires. Can't seem to get the boots to break free of the plugs.

Done. Ended up putting gloves on and just ripped off the old wires and twisted and turned. One was extremely difficult. Somehow I sliced my thumb, but it is all back together and is running well. A couple of the terminals on the coil were very rusty.

It may help to add silicone grease to the inside of the boots - The next time you pull the wires it may go much better.

Blue, from the sound of it, he was replacing original wires/plugs....which is kind of hard to believe at that mileage...there was another post of somone replacing plugs at 250K, but seriously doubt those were original....

Have replaced plugs generally between 30-60K miles(rarely do they reach 100K)...in some cases, you can twist all you want but they won't come off, especially on the later model vehicles that are hard to get at in the rear....in cases like that, I just get a huge pry bar back there and snap the top of the plug off, with the wire, then put my spark plug socket with the double ball swivel to get the other half....

When I got my 99, the plugs had no more than 60k miles and they were as bad as he described his own. In general, whenever I've used the silicone grease on all the boots, I have never had problems with stuck wires or rust. I suspect whoever did his plugs/wires before (probably a mechanic from the previous owner) didn't use the silicon.

The old plug wires say "Delphi" on the boot that attaches to the coil packs. Hard to say about the plugs as I have no maintenance records of any sort, but do have the manual. They looked like they had been in there for a long time. I did use the grease that came with the new plug wires. Should have put something inside the boots too. That's a good idea.

I think while the boots are still easily removed, it would be worth putting the dielectric grease inside to help removal in another 80,000 mile - 100,000 miles.
