I was just told that a code for the pulse coil came up ,does that sound right to you guys?

they should have found the pulse coil issue with a spark check on the first trip

They said there was a error code for the pulse coil and they cleared it but it came back, do you think that would cause the problem I am having? At no wake speed the RPMs seem to jump/serge hi speed is good

Update/ we took the boat out Saturday ran it all day like normal, fishing and cruising from 9 am to 130 pm And no issues they ran it before us too for one hour and no issues they cleared the error code before they ran it also , so do you think it would be good or should it act up again? And if it does act up you know it's going to be in the worst spot for us, What do you guys think? And yes we went fishing and got some weakfish yep you heard right weakfish Thanks for any replys
