1985 Mercedes-Benz 300CD
So I cleaned my ALDA banjo bolt today, thinking "Sweet, things'll start running even better!" It runs great. In fact, it runs so great it just doesn't want to shut off! It shut off the first time I started it after I cleaned the bolt, but the second time I had to press the kill switch. I'm really hoping it isn't finally broken, 'cause I don't have the money to have someone fix it, nor do I feel comfortable fixing something THAT major. Any diagnosis?
