I have a 2014 Ford Flex and its running a little rough & louder while in idle/park. I'm not sure how long its been since the last full tine up. I've had it 3 years and get regular oil changes but not a full tuneup, but was wondering if it might be time for the spark plugs to be changed?

Hey!

 

Let me just be sure. When your car is idle, it kind of shakes periodically, sometimes loud, sometimes not. Does the RPM metre also slightly move with the vibrations?

 

If its a new car, its most probably due to fault Spark Plugs. After 3 years, I think its a good time to get those changed, and you might be happy to see how well your car feels after that.

 

Do let me know if it helps
