My port side engine is strong until approx 2900 rpms, will only run faster with the starboard engine accelerating to bring it up. it is good & strong up to that point. Rinda scanner show no faults & the ecm shows 100% power available. Did the induced misfire test to all cylinders & all are firing, swapped out fuel filters & then the whole cool fuel/water seperator modules. Put a fuel press gauge on the injector manifold & it shows a rock steady 44 psi the whole time, even at 2900 rpm's when it stops accelerating. checked the throttle cable & linkages to verify full movement.

Not sure where to go next, thinking about swapping ecm's. Any advice is appreciated

Have you done a compression check and leakdown test?
Any noise in the valvetrain?

No abnormal noises, havent done a compression test. I figured there would be an oil consumption issue or some smoke & a throttle split if that was the case.

Make sure you do not have a fouled spark plug(s). Might be a good idea to change all your plugs if it's been awhile.

all the above..if all checks out suspect the injectors are plugged..send them out and have them cleaned and checked
