Scotty is right on the money...

You CAN NOT tune around mechanical issues. EVEN if you tuned your car right now, after you fix your issues your tune would be way outta whack.

Fix the issues FIRST then worry about a tune.


Im willing to bet that most of your KR is due to the misfire and fuel being wasted.


Misfires make your FTs see a lean condition since they are seeing a butt load of unburnt air.
