Re: 82 merc 150 v6
I'm not a mech. I found the problem with my rough idle the hard way. I have been adjusting the idle, playing with it to try to improve it but had little improvement. It seemed to load up then run good again. Come to find out after I have no spark and in checking for that I found the ground wires on two of the six coils loose and arching to ground. I think this cause the rough idle from lack of firing and utimatly burned the stator out. Thats where I am now.<br />Good luck!
