"Have twin volvo 8.1 420 hp in
"Have twin volvo 8.1 420 hp inboards. Two problems; one, both hunt [change rpm] at approx 1200-1800 rpm. Have been told that manifold pressure sensor could be leaking but had that checked and not a problem. Second, after long run and shifting gears at idle, both engines occasionally stall out. Idle settings have not changed. Should I just reset to higher idle? [now approx 600-800- rpm]"
