Pls advise ty

 

Welcome to the forums. As for your last concern, I think it's just the car. My 2007 with only 37k on it does the same thing a lot of the time. As far as maintenance, all fluids is a must along with some other things:

-Oil change
-Transmission Fluid change
-differential fluid change
-Brake fluid change/bleed
-clutch fluid change/bleed
-Intake air filter
-VALVE ADJUSTMENT (inspect retainers while in there)
-Also consider cleaneing the injectors, IAC Valve, perform "MAP whack"

Also, read the second post in this thread:

Good Luck!

Oh yeah, and coolant too. Use Honda coolant.
