Clearing the tube is a temp fix..they have a re-designed tube that is the remedy.
Code 11 0n 14 could be a sticking cable or not enough slack @ idle position .. ..they want at least 1/4"..back the adjuster off , clean/lube cable, and clear the codes ..see if it returns
First suspect of DIS ignition misfires @ idle are the plug connector/resistors under each coil. [ or Plats]
