is there a way to test the coil?
At our clubs tech session on Sat one of the techs pointed out a slight greyish are on my 87 300Ecoil(320K miles) and said that the coil had gotten hot at some point. He rec changing the coil. Is there a way to test it? Also when searching under coil I noted other than OE coils eg Jensen. Do I want/ need them and do they fit well?
