I just bout my wife a 95 5.0 Gt the engine starts up just fine and its not missing that i can tell but the motor shakes real bad what could it be harmonic balancer? i have had one crack on me on my old 5.0 what should i do?
If it was driven a long time with the bad balancer it can cause some serious engine damage. I had to replace the engine in my 95 cobra due to a bad balancer wearing out the engines bearings.
