    2014 115 pro xs---eratic from 2800 to 3200 rpm

    I have a 2014 115 pro xs ser# 2b018636--model 1115p73ky. This motor hot or cold starts and runs fine
    under power except between 2800 and 3200 rpm its real eratic (its not in gard mode). Once you pass 3200 it runs smooth at
    any rpm all the way to wot. The fuel pressure is 108, air 94. Checked the coils, firing normal at any rpm. I
    don't know which way to go, any help is appreciated.

    Test the TPS. Are you running a prop such as tempest with only one plug in it? Has it always done this?
    Describe erratic as you feel it
    Thank You Leon Pugh
