Hi everyone, just in the last week since its gotten a little colder here in Ny Im having starting problems with my1987 300 d turbo 124. It now takes 3-5 starts and then I have to hold the starter over and let it crank longer to get it to start. Then I have more smoke than normal. Would injector cleaner help then checking the glow plugs or does anyone have any ideas for me? Any help would be appreciated. . .Thanks Bob
