Got in the XFire this AM, started it up...seemed to take a couple of extra revs to get it started...let it idle for about 30 seconds, shut if off, restarted it, let it idle about 2 minutes, then headed out of the complex. I get to the street, and give it what I call a 'normal' amount of throttle, and it felt totally different (always wondered how you guys got to burn rubber!) Then, when I got the the light, it sputtered for about two seconds, then ran normally again, except for the gas mileage, which Torque was indicating was off...
