2010 Lincoln MKX P0430 Code After Spark Plug Replacement
On Saturday, I replaced the spark plugs in my 2010 Lincoln MKX. By Sunday, the check engine light activated with fault code P0430. I'm concerned whether this code is directly related to the spark plug replacement. Could the new plugs be causing or triggering the P0430 issue?
No immediate answer here. Could you clarify why you replaced the spark plugs? Was there a specific problem that prompted the change? Also, what type of spark plug did you install—OEM or otherwise? This information is important for diagnosing potential connections to the P0430 code.
