Hey guys, I have a 93 OMC 4.3 liter. Problem is it will not idle below 1000 rpms. It appears that one cylinder is not firing. Spark plugs changed and no difference. Spark appears to be coming from the wire, but I planned to change the wires next. Compression is good in all cylinders just can not get the #3 cylinder to fire. Boat runs great above 1000 rpm, WOT runs 4400 rpm. Just wont run under 1000 at idle. Any suggestions and or ideas to figure this out would be appreciated
Thanks
Thanks
