[QUOTE="Psykit, post: 665305, member: 25223"] ICV was clean and flap has free play too. Shouldn't be the ICV. Idling was fine, RPM reading is steady. But can feel vibration pattern. DISA flap was in good condition. The seals are worn but RTV sealed it nicely with the manifold when reinstalling it. Any possibility of O2 sensors? Anyone replaced O2 sensors and see improvements in terms of hesitation and vibration? [/QUOTE]
