Engine doesn't stop when you turn the ignition off
Last night I turned the ignition off, but the engine kept running. I hit the emergency stop engine lever in the engine compartment to killt the engine. This problem happened once before on a routine oil change. The guy changing the oil dissconected a vac. line. Today I noticed it stopped the engine when I turn the ignition to the off postion, but it was kind of sluggish. I also noticed that the door locks were sluggish as well. Are these systems related? Where would I begin looking? Any suggestions woul help.
