Age old question. Rough idle and stalls. WOT runs find. What’s been changed: new compressor, tracker valve, fuel regulator valve, plugs, plug wires, all coils, all fuel injectors, new agm batteries, fuel/air pressure checks, compression check. Took it to a boat mechanic and they messed with increasing idle speed and I believe linkage. Mistake in my option. it’s still idling rough and I don’t like it idling at 1000 rpm. I get TPS fault codes now in my Mercury view. Any suggestions. I’m going to replace the TPS and try to put back the settings on the linkages that they adjusted. I have a service manual hopefully to help. What started this whole idling issue was a blown ignition coil which it may have been one of the coils that Mercury had issues with. Ever since then the engine has had rough idle and stalling.
