I have a 1998 Svt that popped up a 420 CEL code at about 90000 miles. It was just returned to me from a service visit where the front wheel bearings and rotors where replaced... Now it has a vibration at 2500 rpm and the mileage is down.... What should I do first??... Should I be driving it... ??? Thank you..
