Carbon Clean Out

So installed a tune, did plugs and coils before hand, car is hesitating when accelerating, like stuttering . Started before the tune and was hoping the coils, plugs, charge pipe would do the trick, but no change.. Car has 90K on it, no idea if it ever was done before cuz I am the 2nd owner and bought the car at 67k.

Turner wants $650 for walnut blast, any other cheaper but quality recommendations? Also, think this is the solution to my problem?
