the motor runs well in all phases of operation except when throttling back to neutral. when placed in gear the motor wants to stall at low rpm.no buzzers or alarms just extremly rough idle . the problem dissappears when i shut down and restart the motor. i have trolled at low speed for hours taking the motor in and out of gear without having this occur but as soon as i increase my speed 4000rpms to move to another area and back down to neutral the problem returns. i have checked for fuel problems,and using ring free additive ,checked fuel filters, plug wires all ok . All shift and throttle are ok. Could it be a shifter switch or thermal sensors or is something else going on? Motors have approximately 450 hrs. Appreciate all help.
