Got a 2014 90 hp 4 stroke mercury outboard
I started having issues with RPMs on neutral , going up to 1800 , i changed the IAC valve and problem was solved but another problem came up. When shifting forward only ,
No throttle,RPMs go up to 1600 , same thing in reverse,
Changed shift position sensor , no change
I disconnected throtle and shift cables and shifted manualy from inside engine, same thing
I checked continuity on harness from new sensors and also all sensors and i got good readings
Im running out of ideas here
Mechanic plugged computer and it shows no faiults
Deffective new sensors?
Bad relay somewhere?
I have the service manual in hand and im
Following all tests explained on it
Any help is appreciated
Thank you
