Went out today to start the pure and it would just crank not even a hint of starting. Smelled like it was flooded. No check light. Scratched my head and remembered I had an 80's Honda that would do this if the air filter was clogged.... Pulled the filter put in a new one and fired right up. Filter was DIRTY to say the least.... So I'm thinking I'll be replacing the filter at 10k regardless of condition I'm at 17K now. And I just made a comment in another thread that our '09 seemed peppier and made the comment maybe the air filter needed changed...guess I was right!
