My 2008 Honda Fit has 185k on it. When started cold it misses so bad that when I place it in gear, it stalls. After It warms up the miss goes away. It is a sport with automatic transmission. I have replaced plugs, coil pacts, pcv valve, serpentine belt. Check engine light does not come on. I have not adjusted the valves.I need to know what I need to do next?

 

The coolant temperature sensor may be bad.
