Wonky Glow Plug Light
So my glow plug light likes to illuminate sometimes after startup. As in, I'll be driving and suddenly there it is, shining back at me. Does it illuminate when I start it the first time? Thanks for asking, because no, no it does not. I don't generally have any issues with it starting, as A: I don't drive it when it's cold and; B: I still wait before I start it. I know that I should track down the latter issue, but I am (perhaps incorrectly) more concerned about it warming while running.
Car in question is a '91 350SDL with a 3.0 OM603.
