HELLO, First timer. 1999 ficht 150 has been flawless. developed a slight gallop at cold start up. Idle a bit uneven at most times. no codes.New reeds, had injectors checked and cleaned.Still same problem. Would guess fuel pressure check in order. Thanks to all reply's and suggestions

Most of the efi motors I've run into have, an idle air control valve (iac). I would have looked up your parts pic to see, but boats.net changed their parts Web page, and am unable to see the parts pics now.
But, if you have the iac valve on your motor, check the manual on how to clean it. I've known a few iac valves to cause these kinds of issues.
Good luck, wish I could be of more help to you. -
if you prime the bulb during the rough idle does it clear up? if so then its either the tank/fittings/hoses have a leak or the LP fuel pump is failing. ***uming the gas is fresh (not more than 2 weeks old).Comment

full tune up. 25 psi fuel pressure. pumping ball wont help injection. Doesn't have idle air control. overall running much better but still not perfect. random dip in rpm at idle, aprox 100. Old school says possible weak coil, but there are 6. Computer and injectors good. Thanks for inputComment
