Having problems with my motor dropping rpms while running. I can be running wide open or half throttle and the rpms will drop. It does climb back up to ordinal rpms that it was at. Motor is stock. Has anyone else had this problem?

I'm not sure as I dont have experience with the efis yet. But I'm assuming your engine still have Briggs warranty?

One of your wire harness could have an issue. You also could check that your vent on your gas is open and/or check to see if you have bad gas or water in your gas. All can cause same issue.
