It’s been running lean and has recently hesitated to start back up again after driving it. It also begins to overheat when in idle for too long (more than 10-15 minutes) Mechanic's Assistant: Have you checked the [coolant](/topics-coolant-nissan/)? Have you checked for a leak in the cooling system? The coolant level is fine and there isn’t a leak in the cooling system Mechanic's Assistant: What is the make/model/year of your car? 2014 Nissan Juke Mechanic's Assistant: Are you fixing your Juke yourself?

No that’s it
