    Mercury 40hp 4 stroke Idle problem

    When the fuel filters and plugs were replaced, the compression checked out good. When this failed to correct the problem, I tried replacing the air solenoid, unfortunately that didn't help either. Only run non ethanol gas. It is a 2018 motor.

    Mercury 40hp 4 stroke Idle problem

    Runs great at speed, kills when at idle or slow troll speed. Changed plugs, fuel filters, and oxygen intake valve. Still doesn't fix the problem. Any ideas on what else could be causing this. Thanks.
