I recently had an issue with a pinging sound coming from my engine my Hanes Manual said to remove the spark plugs one at a time. Turn the engine over and see if the problem continues. And that's the problem area.
However what I couldn't find was which plugs mean what.
Luckily my first one was right. It was the 3rd one in from the windshield. I was guessing it was a piston problem. Someone please tell me that's not what it is.....
