Clearly, whoever serviced your car should fix this but you have already been there twice. You didn't mention what service was initially performed. Hopefully service was not received at a Honda dealer. Maybe another Honda dealer could help. I know my suggestions are not much help. Sorry.

I believe NGK iridium spark plugs are specified for a 2008. NGK website shows part number as IZFR6K-11S. These plugs come pre-gapped at .044”. I have read that use of other spark plugs is not recommended and can cause performance problems. Be advised my 2008 still has original spark plugs and I have no personal experience changing them.
