1996 150 EFI. ser#OG351951. The motor requires extra throttle to start, then runs rough at idle and dies unless I put it in gear and give enough throttle to run. It was doing this along with not charging and radical tach reading . Yellow wires coming from regulator were burnt at connections. I replaced one of the regulators and it corrected the charging and radical tach issues and for the first few starts, the idle problem. After a few starts of motor, it needs extra throttle again. Recently replaced the ECU with one from Brucato. I don't know if voltage regulator has anything to do with the starting problem. Wondering if I should replace the second regulator since motor is charging 13 to 14 volts and tach reads normal now. Compression is 115 on all 6 cyl. new plugs, cleaned the filter for the fuel pump in the vapor tank, new water separation filter, new bulb, checked pick up tube in tank for restrictions. Could this be a dirty injector or one that's not getting current at low speed? Spark has been recently checked by mechanic but not since this starting/idle issue. Any ideas?
