Engine Performance problem
2003 Saturn Vue 4 cyl Two Wheel Drive Manual 92000 miles
starts runs rough smooths out 3000 rpm. Has codes p0440 evap emissions, p0481 cool fan circutit 2, p1599 a/c press. Switch low. P1512 batt sense line 2, p1682 charging system low. The reduced power light is on with SES light. A new $550 cat. Converter was installed. The vehicle will not go over 35 mph. This is a drive by wire system. It does not seem to make any difference if you are half throttle or full throttle. Could it be the throttle position sensor on the pedal?
