Mazda MPV: Error Codes/TSBs/Recalls
We then brought it to a dealership, and they told us that they believe that a valve is not sitting correctly on the 4th cylindar. (We now have only error code 304). Specifically, they say that the cylindar has low compression, and the exhaust valve is slightly burned out to cause a misfire. They need to remove a cylindar head and do a valve job. The cost will be approximately $3200. We have already paid $700 with no luck in fixing this error code. Any ideas?
