Could it be paint from the cool fuel module clogging the injectors? Mine is laid up right now for, among other things, replacement of the all injectors for that reason.Ran injector cleaner through the fuel system with no change.
I was considering changing all the fuel injectors unless there's a way to identify if any one particular bad injector?
Had the same problem two weeks ago. Two bad injectorsI'm having an issue on my port engine ('05 8.1 Horizons). Last week I noticed significant throttle "lag" on the port engine. I cruise around 3400 rpm and to get the port engine up to 3400 to match the starboard requires significantly more throttle. Temps, pressures, etc., all OK and runs smooth with no alarms. It just won't turn up. Had the fuel filters changed and it was fine. Next day the same problem. Could it be the Cool Fuel module issue? Before I spend a lot of bucks and loose a lot of water time, if not the rest of the summer, having a mechanic tear into it I thought I'd seek opinions.

If you pull the injectors you can try to have them professionally cleaned and flow/balanced tested. Maybe they can steer you to some aftermarket injectors. The merc replacement are ridiculously expensive.
Here are some DIY videos, but the pros use ultrasound which may be the key.
$200 to clean, or $349 new, I might go in for the new ones as well.Don't these look like they're genuine OEM Injectors that'll work for a 2005 8.1?

For that money I'd just buy 8 and install all new. Maybe get the old ones cleaned as spares going forward?
