So I need more opinions and more thoughts. I've been chasing a vibration coming to the Ford focus for the 2000 to 2008 generations and I've done pretty much everything you'd think that you should do and then some. I've changed cracked ignition coils, all the motor mounts, I've changed the harmonic balancer idler pulley tensioner pulley and serpentine belt, car had the wrong battery when I bought it from the guy who owned it before me so I put the Right one in. I changed the PCV valve and I maintenance it regularly. Anybody got any ideas? I can't seem to get this vibration to stop. Feels like a go-kart.
