I will definately do that, sounds like it would probably do the trick. I know that marvel mystery oil has a reputation of doing amazing things. I tried unplugging the coolant temp sensor in the intake and that stupid light still stays on, even with the keys not even in the ignition. The only time it goes out is when you unhook the battery. Weird. Could it possibly be a fuse or something? The accompanying gauge seems to work fine.
