Motor still running after turned off

Asked by Stephen Jan 17, 2020 at 01:00 PM about the 2007 Lincoln MKZ

Question type: Maintenance & Repair

When I turn off the car the motor continues to run
for a few seconds after the car has been turned
off and it sounds like it's slowing down like the
motor is still spinning. And the idle seems off by a
little as well

That problem is related to igition timing and low grade fuel. Also refered to as pre ignition

Get the engne serviced, particularly ignition plugs and points if you have points, use a fuel grade of 95octane or higher, sjouod solve your problem, i had simular problem on ford v6

If it diesels a lot I suppose it could hurt it but I would not worry too much. Witwillem is right that higher octane gs might reduce the problem but the rest of his advice is rubbish.

I found the issue I have a radiator fan that's got sum broke blades most likely from the raccoon I hit. And since there is to fans and it's winter would the motor stay cool enough if I unplugged the one fan until I replace it

The car will probably run cool enough in the winter. Don't neglect to replace it while the weather is still cool.
