Answer 1

P0306 Misfire number 6 cylinder

Fuel injector cleaner with a vehicle with a misfire does not help. unless the engine is in good condition. When there is a misfire that cylinder is not contributing, this can be from a igntion problem to a fuel injector problem to even a mechanical conditon such as low compression.

 Misfire condtion , the most suspectable is the igntion coil pack as well as the igntion cable and even the sparkplug. use another igntion coil pack
