I was looking a few weeks agoe at my maint schedule for a 14 Civic and it had listed B134. Today when I looked at it, the Item #4: spark plugs is no longer showing. Never saw it do this before. Any ideas, I have around 156,000 km's.

 

might be a code that was picked up, then cleared, but may still be in memory. if you can get the code reader, it may still be in the memory.

 

Thanks.
