2005 Wrangler Jeep advise needed

The car rear ended another. Most all has been repaired. The engine was even replaced. The mechanics don’t know what to do about the fact that it still randomly stalls when doing a 3-pt turn, parallel park, …[more often in reverse]. Also, when traveling 65+ mph the speedometer bounces rapidly between 65 and 70 mph. Have not tried over 70 mph yet.

Please advise.

Sell or trade this vehicle, ASAP. You’ll never have the Jeep you originally bought after such a severe crash. It’s been damaged irreparably. There’s nothing you can do. Sell it before it bankrupts you.
