this is a problem I have had since new with mum's 05 euro and I also have this with my 05 euro. Both are manual.

I complained 10 times to my workshop controller when I was at a honda dealer and he was speechless. Was told by others in the workshop to try different premium fuels. A fuel pressure reg was done on mum's under warranty and did nothing. Put reports into Honda and never got anything back

FYI mum and I both have the hard start when hot, usually when the car has been parked for up to a few hours.
