"We have an '02 4.3L MPI C
"We have an '02 4.3L MPI Chevy engine (app. 120 hours). This season it's developed intermittent issues--running rough, missing, low power, loss of throttle. We've replaced almost everything but the ECM. Has anyone had any luck with using an automotive ECM ($400) instead of the marine ECM ($1800)? Any input would be appreciated. Thanks."
