I have a 2003 Yamaha hpdi 225. Fresh powerhead about 25 hours ago. Had the injectors flow tested and cleaned and now it’s not wanting to idle. I’ve noticed it idles good for the first few minutes then it starts to idle rough and die. Engine runs great on the top end just rough idling and in gear. Any suggestions so I don’t have to take it to a shop? We have always used Yamaha ring free and fuel additive and mid grade fuel.
