Just thought I'd let you guys know...I got my xfire fixed! A friend of a friend had a mechanic that suggested we start with the feul filter. I must be living right! The filter was $85.00 but it took care of the problem 100% I've had this car for three years and thought it was quick, what I didn't know was really how quick it could be if it was runnig right. WOW what a difference! Problem solved.
