Hi 93hondapreludesi,

Thank you for the donation.

Did you clean the throttle body, idle adjust screw air passage and IAC? If yes, then I would recommend chaecking/adjusting the valve clearance.

The difficult starting is most probably due to an intermittently failing PGM-FI main relay. Remove it and resolder the circuit board and retest.
