Read through most of the search threads, but will seafoam work okay in a 2013 ram hemi? First remedy will be seafoam and high test gas.

How do you know that you don't have a fouled spark plug, bad wire, coil pack or a bad injector for example? what makes you think seafoam is the solution ?


Seconded... before you start shoving chemicals into the tank, you might want to check and see if it's not something dumb-but-easily-remedied (and which would carry way less risk).

Most folks who ran the codes for me suggested bad gas/water-in-tank as first/ easiest test, then coil, then plug, etc, etc,. So did a couple of youtube videos. Are you saying I should start changing parts first?
