Engine miss under hard acceleration can occur if Turbo pressure is too high. This can happen if the control-pressure pipe from the exhaust manifold to the wastegate becomes clogged by carbon or ice. To reduce this clogging tendency, the hollow bolt connecting the control-pressure pipe to the wastegate has been enlarged from 10 mm to 14 mm diameter.
