Sticky Thingamajig, Engine won't turn off.
Please forgive the ignorance on all items in the engine compartment but I am experiencing an issue and am hoping the esteemed members of this forum can help me diagnose.
I've got a 1976 300D with approximately 120,000 miles. I've owned it for 3 years and it is in very good shape. It's my daily driver. I live here in Scottsdale/Phoenix and it's been cold for the last few days. Right now I am parking the car outside at night where the temp is dropping to the low 30's.
Yesterday when I fired the car up in the AM and drove it to work I had to stop at the market just 3 or 4 minutes away. There the engine wouldn't turn off. This is not the first time the engine lingers a moment when the ignition key is turned off, normally I just turn the key and remove from the ignition and the engine will continue to turn only for a second but always stop. I was told this had something to do with the old vacuum system.
This time is different. The engine stayed running. And running. And running.
I immediately drove the vehicle home and tried to shut it off again. No success. This is when I popped the bonnet and pressed the lever that said "Stop" near the valve cover. This killed the engine.
Is this condition created or exacerbated from the cold weather? If I drive the car and get it to warm with this fix the problem? Or is there something more sinister going on here?
