1998 Sea Ray 370 Sundancer with 454 MPI Horizons. Approximate hours -600.
Port engine burns 20% more fuel at idle and underway compared to starboard engine. Had a scanner checking for codes and data. There was an error code for a faulty TPS. Also the port engine "surges" up and down in idle or less than 3-4 knots. Neither engine burns any oil at all so I'm not concerned about valves and rings - yet. Also when engine was scanned and throttle was put at full wide open the TPS registered that it was only at 85% open. Port engine need more throttle to bring rmp's up to same level as starboard.
Could this be the cause of my fuel burning issue?
