New engine in the boat, (454 mercruiser in a ‘87 cobalt). Having a slight issue. Once the engine warms up I get what im assuming is a misfire (engine studders) between 1500-2000 RPM while at the same time the needle on the voltage gauge bounces around like crazy. Any ideas? Where would you start.
also I’m getting engine feed back through my speakers.
obviously an electrical issue, all my grounds look good, batteries are all good. I sanded all my ground contacts nice and clean with no change.
thanks in advance!
