Agreed, and again i didnt read his full discription of what the cause was. Of course coolant in the oil would make the motor run/idle rough or not even run at all or shut off quickly once started(fouling the plugs). But me saying coolant, I was obviously reffering to a different motor issue, which is my fault for not reading the discription clearly....No biggie
But i have delt with diesel engines for years while in the US NAVY....Dieseling can be very dangerous(depending on your situation or location)
