Hey all new here, just got this 1996 subaru legacy outback about 5k miles and 4 months ago... Great deal and only work I did so far after oil change was a head gasket sealant liquid to stop a slow leak of radiator fluid, which worked great and haven't had any coolant leak since.
However, just yesterday, as I was driving to work, I heard a loud bang and engine started running rough, shaking and sputtering. Pulled over, got a ride, came back to look and found the spark plug with holder completely loose and i just easily pulled it out to look at it.
What I'm wondering is why the spark plug fell out, no stripping it looks like, and also it looks like it melted around the holder? Do I need to get new spark plug wires as well as new spark plug? Going to try to fix it soon, it's my daily driver for now for my 15 mile commute, but I'm not really able to dump a ton of money into this.
Thanks for the help.
