Just got my new Xfire up running and on the road a couple weeks ago and I have a new noise around 18 MPH does not always happen but when getting up to speed slow i can sometime hear what sound like a churping or squeak. Almost sound like a u joint however the Xfire don't have them. It does not sound like it is related to RPM as much as speed. I'm thinking speed cable related But, once again does not have one of them. Wondering if anyone has had the same thing and what it was. fun little car to drive.
