ok so when I first start my mustang the motor run smooth with no issues, but after the car runs for about 30 to 45 minutes when I bring it back to idle I have a engine vibration that slightly shakes to whole car. what could cause a vibration only at idle and only when its warm? I can't feel it when I start driving again and don't notice any power loss.
its a 302 that has been refreshed just did a 6cly to V8 swap.
Thanks for your time
