Earlier in the year you talked about a stuck fuel injector being the cause of a throttles not syncing. I have a similar situation and was wonder what othe diagnostics would indicate this problem? Would it show up in the codes? I have Mercruiser MAG 350 MPI Horizon engines. The throttle levers are slightly mis-aligned when under 2000 rpm, but when accelerating to bring the boat up to plane, it becomes more exaggerated. Moving the throttle forward does little to increase rpm above 3300. Once on plane, rpm is more responsive to throttle. I've had the codes checked on that engine, but nothing comes up. Fluid levels OK, starts fine, does not misfire. I've had a new fuel pump and sensor during spring commissioning....as fuel pressure was a bit low. Compression is OK and within spec.
Any suggestions?
