Mazda Tribute misfire

Some 2011Mazda Tribute 3.0L vehicles with an engine build date of 12/21/2010 to 1/7/2011 may exhibit a misfire or rough running condition, and/or DTC P0301 (cylinder 1 misfire).

1. Verify the concern.
2. Determine the engine build date. Refer to MS3 online or workshop manual section 01-10C ENGINE – 3.0L. If the engine build date is 12/21/2010 to 1/7/2011, proceed to Step 3. If not, refer to LS3 or the workshop manual for normal diagnosis.
3. Determine the right hand cylinder head manufacturing time and date. An ink jet stamp is located on the intake face of the RH cylinder head, under the upper intake manifold and can be viewed by looking over the front engine mount. The stamp will read FFV80 HH:MM MMDDYY. If the stamp reads 14:30 12/21/2010 to 14:00 1/7/2011, replace the RH cylinder head. If not, refer to MS3 online or workshop manual section 01-01A MISFIRE DETECTION MONITOR.
