All, My dealer claims this is 'normal' on my '04 Mustang GT... At idle, every few seconds, what I can only describe as a shake goes through the car. Basically, the whole car vibrates for about a second every 4 or 5 seconds. Its not a horrible shake, but pronounced enough that I can easily feel it...
Anyone else have this? Is it normal? If not, anyone know what I should have my dealer look at while its still covered by warranty? I have a feeling its normal right up until I have to pay to fix it, then its gonna be a huge thing..
