500 HP Intermiten Idle Issue
I have a 2003 Powerquest with 500 HPS: (500 EFI's)
* Intermittingly the starboard engine revs to 1500 RPM (I shut the engine off restart - issue goes away) It will stay at 1500 RPM and will not drop down
* I can be running the boat all day and then when I come off plane - the same issue occurs (Shut to engine down - issue goes away)
* It will happen at no specific time
* I have replaced the batteries, check the battery connections and ground connections
* The ECM modules have been tuned by Arizona speed about 6 yrs. ago
Comments / Possible solutions / Feedback is greatly appreciated

Walzman
