After sitting for a week or so, I drove my atlas all around town for 2-3 hours today. I decide to go out for a late night drive, first thing I notice is the car jittering/shaking when parked & idle. As I drove it progressively got more noticeable, and I had to limp home. I’m not 100% sure if the warranty is still active. I don’t want to risk it and drive to an auto parts store. I thought about replacing the spark plugs & ignition coils myself since I’m pretty certain the car is at 70-80k miles. Then again, I don’t want to spend the time doing that and it end up not being the culprit.

What do you recommend I do?
