Re: LQ9 misfire.. No codes or CEL

Does it sound like it is misfiring? Or does it feel like it is by sitting in the cab? I thought mine was too, it felt like it had a ruff idle sitting still. I popped the hood and noticed my harmonic balancer wobbling a bit. Dealer also told me it was normal. You could clearly see the idler jumping around correcting it. Idiots!
