I have a 1985 300TD and i can take the key out and it doesn't stop. If I press the lever on the engine it does turn off. I'm pretty sure the problem has to do with the vacuum system but I don't know how to test it. Could someone please send me a diagram of where the vacuum system is and instrustions on how to test it. I'm also leaking from a fuel injector could that cause my problem?
