The engine computer on a FICHT is raw water cooled. Look at your ECM and if its got fins on it its air cooled, if its got hoses going to it its water cooled.
The passages that cool the ECM get clogged with scale and the ECM gets hot at high RPM's and starts to throw codes and kill the throttle.
Will idle all day but wont let you run around at high RPM's.
Fixed a couple here on the Cape by just taking the ECM off the motor and cleaning out the passageways. Worked every time.
Worth a shot at least.

this is true - the EMM indeed is water cooled,however,when the EMM "cooler" is clogged - the motor will go into limp mode,dropping the RPM to 1,800,alarm will sound too
another point of clogging is in the fuel cell - fuel cell is sea water cooled as well
those problems are related to FICHT motors/DI motors - not sure if this is a FICHT motor
i'm guessing a "gremlin" is an intermittent problem ? the motor shuts down,and refires after sitting a few ?
