having no codes is not the same as actually using the scanner properly to monitor the various sensor values and functions in real time.
with the factory workshop manual, the scanner and a VO meter this problem is identified and fixed in 1/2 an hour.

Adjust Idle - 502 Mpi
I have three 502 MPI Magnums (circa 1998) in my boat. Any way of raising the idle on these? i'd like to raise them 200 RPM's for better control while docking but don't want other complications as they run good otherwise.
