Walnut Shell Blasting

Called the dealer about hesitation while accelerating aggressively and know based on the threads it could be a cylinder misfire or carbon buildup.

Dealer will look at plugs and coils packs but said if the carbon build up isnít bad they won't do the Walnut Shell Blasting. Cost to do the service is 640.00 dollars and will take 5 hours, is it worth it just to be cleaned out?

Cobb Stage II +FMIC aggressive is when it's the worst though still noticable in Stage II Sport.
