If you don't think it is the computer do you have any other ideas or checks I can do? I looked at my iac at idle and was afraid to adjust it after the book says 0-40 counts and Jim at Arizona speed said my 34 was fine. Any thoughts on a wiring problem? I've tried to visual check all the wiring for shorts or melted wires. I just thought since my alternator burnt up one day then the boat started running bad the next might have something to do with each other.
Thanks for the advice
