2000 9-5 bucks at certain RPM
car bucks at 2700-2900 RPM in every gear. Accelerates smoothly up to that point, then feels like a fuel cut. Checked for throttle limp mode but the cable is still independant of the whole assembly, and disconnected the battery for 30 minutes to reset the check engine light. The check engine light comes back on immediately. Ive searched the forum but an O2 sensor seems the only other thing mentioned. If i simply unplugg the o2 sensor can I check to see if the vehicle operates correctly or will running the car like that damage something. And is there a way to check the codes without going to the dealer? Thank-you.
