Hi Everyone, first time posting here and happy to contribute!

I have a 2014 Honda Fit (190 000km, automatic) that has a stalling issue when the engine is cold.

The car starts fine in the cold, with the cold engine icon being displayed on the dash. If I put the car into gear while the engine is still cold, the engine lowers rpm quickly down to ~500rpm and rumbles/putts for a few seconds before completely shutting off. I have the restart the car and let it warm up before moving. Sometimes I can put it back into park before it stalls, where then it rumbles at ~500rpm for a few seconds before idling back at a higher rpm. Once the engine is warm (and the cold engine icon is gone), the car acts normal.

I have replaced the battery, alternator, spark plugs, and just recently the engine thermostat with the problem still occurring (no codes showing as well). It is a little annoying to wait for the car to warm up every drive, especially with the long and cold winters in Canada.

I am at a little bit of a loss as to where to go from here. Does anyone have any ideas? Thanks.

 

Have you checked the grounds? They should be clean, without corrosion. If needed, replace them.

Are the battery connections good, tight and without corrosion?

 

Thanks for the reply. Yes the grounds are clean, along with the battery connections. Battery was replaced a few months ago when I first started seeing the issue, so I hopefully eliminated that being the issue.

 

I had the same issue and a valve adjustment did it for me!

 

Thanks for the reply. I have seen a few suggestions of that in other forums, so I think that is the next thing I will try!
