Fuel system cleaner

Techron is the only effective fuel additive. Will clean intake valve and combustion chamber deposits. In my experience the only cure for injectors is replacement. I've run into that with both the 01 and 09 at 160-180K. They have always been run on top tier gas. They were setting codes for misfires which turned out to not be coils.
