I had a direct injected Mazdaspeed6 and at 84K miles I pulled the intake manifold to clean the valves and they were really bad. A combination of EGR carbon + PCV oil residue and no fuel washing because of DI is a bad combination. A lot of Mazdaspeed DI drivers will disconnect the EGR and run the PCV through a oil catch can to try to keep the valves clean. After cleaning part throttle drivability was much better but full boost power "felt" about the same. |
