Q: car shimmering a little and goes slow until you pass 20,000 miles

Could this be needing new spark plugs tune up

My car has 56000 miles.
My car has an automatic transmission.

Hello. Engine performance issues such as trouble accelerating can be caused by a wide variety of issues. If the vehicle has not had a tune up in several thousand miles, it may be possible that a thorough tune up will solve the issue. Similar symptoms can be caused by faults with the fuel, ignition or engine management systems. If the Check Engine Light has come on, I would recommend having the trouble codes retrieved, as that may shed some light on what the issue may be. If there is no Check Engine Light, then I would have the relevant systems inspected to pinpoint the cause of the shimmering. Additionally, if it has been over 20k miles since the last tune up, I would also consider having a tune-up service done soon.
