2015 C300 Won't start
Did a spark plug change, pretty easy to do. Started the car and it started fine, I let it idle for a few minutes, then drove it after a few miles it started to misfire and now it won't start... Any ideas? I checked they were the correct plugs to start and have taken the boots back off and placed them on again to make sure they were on... which is pretty hard to tell.

Have you tried disconnecting the battery and reconnecting it? if you have tried that and it still does not fix the issue, I would think it would be a defective plug or a worn out boot. Had this happen on my LS400 that I had. ended up just being one of the boots that got condensation in it.

So I found one of the new plugs busted up, which is weird because i used the same torque on all of them... Still starts but runs very rough. i vacuumed it out the best i could with a vacuum and pipe before retrying...
