My car has an automatic transmission.

Hi there:

That’s an interesting issue you’ve got going on with that Maxima. The best way to diagnose this is for a mobile mechanic to complete a check engine light inspection. Although the light might not be activated on your Nissan, this inspection will permit them to download any error codes that might help them pinpoint what’s causing this problem. It’s possible that an electrical sensor or wiring harness is faulty or sending an electrical short to the ignition coil.
