Wrong size spark plug.
« on: January 09, 2020, 10:46:35 PM »

So I lent my car to a family member who decided it was wise to put the wrong size spark plug in one of the cylinders before realizing that they had to use a different socket size to install it. Of course the car had been misfiring since. I got it a few months later and have had it for a month or two and am trying to rectify this situation now, what kind of possible future issues should I look out for once I get this changed.
