Check engine light - found leaky exhaust. Replaced pipe from catalytic converter back. Check engine light still on |
| 97800 mi | Soon after purchase, the check engine light came on (P2178 too rich off idle) with no other pending or trouble codes. The engine runs a bit rough at times with low fuel economy. The garage I purchased the Mazda from replaced the MAF sensor and the Mazda genuine oxygen sensor to no avail and they do not seem to have an idea how to solve it. |
| 97500 mi US $80 |
The error is too generic and I don't drive enough (~3k miles/yr) to make it my highest priority. So I am just following the troubleshooting guide from https://www.autocodes.com/p2178_mazda.html and replace/cleaning small things I can myself when I want to. Cleaned throttle body and replace spark plugs. I found the #1 plug was covered in oil so the valve gasket replacement is needed. But I won't do it before I replace the PCV valve, which is apparently not an easy job due to its location (underneath the intake manifold). Perhaps I will get to it when it's warmer outside. |

oxygen sensor failed. It may have been a replacement part but I did not report it prevoiusly. |
| 39680 mi C $100 |
Engine light went on again but mechanic and I agree to ignore it. I goes on for a while, then off for a while (days, weeks), but nothing seems to be wrong. It doesn't flash and there is no correlation with anything, so I'm not worried. |
