The car is a 1979 300D, I was able to get this car running (sat for 9 years) and she runs great, but there is one problem. When you turn the ignition off the car just keeps running, Key out of ign. keeps running, battery unhooked, keeps running,

So where do I start looking? I have heard of this before but was unable to find anything when I did a search!

Thanks!

Unfortunately it ran out of fuel before I figured out how to stop it... JOY time to bleed the air...again!
