Embarrassed by Spark Plug Condition.

[Blown]

I have had plugs and wires sitting on a shelf for 6 months, since I bought this X.............. It started running a little rough so I did them yesterday. The old plugs had a nice tan color but the gap was worn way open! They are just worn-out and likely the stock motorcraft plugs and wires with 135,000 miles on the clock.

Here's a representative though some of the plugs center electrode was worn down to the level of the insulator:

Anyway, it's done now and I noticed a little better performance. It idles better and no longer stumbles coming off idle. I should see a little better mileage.

She got new hoses, flush and water pump last month.

Next I am going to drop the tranny pan, clean the solenoids, add a drain plug, and refill it.

Wow, definitely overdue. Glad you got them all out in one piece, some others haven't been so lucky.

Wouldn't blame the Motorcraft plugs for breaking, more like leaving them in too long in a harsh environment.

Ugh - spark plug issues - snapped clean off, ez out snapped

I had more issue with old plastic plug wire retainers breaking. I guess I got lucky, they all came out easy.

The new ones went in with anti-seize on the threads and dielectric grease on the other end.

I am amazed at 135,000 mile plugzzzzzzz. Damn good ignition system!

Well done, good for another 50k miles. I just bought a 92 Lincoln with 52k miles on it, with original plug wires. I'm betting the plugs are original too, but I only bought plug wires so far. It has a leaking radiator, so Rock Auto was the place to get that and all hoses, a belt, and T-stat. People are proud of the original parts, I'd rather have newer than 25 years.

Don,
Ya newer like my 17 year old, ha,
Soon I will be able to spank most SUV's with my old X and have seen your old projects. Fun stuff.
