Hesitation and/or a lack of power can be caused by the secondary shutter valve (SSV) in the intake manifold becoming stuck open due to carbon build up around the SSV shaft. This may occur with no Check Engine light illumination but eventually the light will illuminate with code P2070 (Secondary Shutter Valve [SSV] stuck open). The cleaning procedure described under the service bulletin is a long process and it is recommended to install the updated SSV actuator and gaskets. The SSV is activated at higher RPM and the carbon accumulation can happen when it opens infrequently. The effects RX-8's built before April 18, 2007.

Mazda has issued Bulletin No. 01-010/10 for the above issue:

• For VINs JM1FE****** 157838 to 403405 (built on or after July 1, 2005), replace the tank only.
