On a 2004 ford explorer v6. I had a mechanic tell me the rear timing chain guide went. Upon getting my vehicle to the house I noticed a single spark plug sitting on the front deck on the plastic gutter piece, and looked at the engine to find a spark plug wire hanging free with an empty spark plug hole. They told me they did the work I asked, and had it running, then it began to sound odd and stopped running. Is it possible they screwed up?

    It seems clear they screwed up by returning the car to you with a missing spark plug. I'd find another mechanic!

  • If you were missing a plug your engine should have been running extremely rough, did you notice this?

  • Yes all six are necessary, there are no spares. I'd take it back and demand a refund. I don't think I would give them another chance to "fix" it.

It's clearly an issue on their side. A spark plug does not blow out of the engine alone, the spark plug would be shattered at minimum.

Get the best refund you can, reinstall the spark plug and try a different mechanic.

What I don't understand is that you have been able to drive back home like this ?!
