My 2000 9-5 Aero seems to be running fine but on the dash it shows traction control off and a picture of an engine. The error codes are P-1251 & P-1260. After I erase the codes they re-appear after several KM of driving. Also I have noticed that just before engaging the starter a clicking sounds comes from the thro ttle body. After reading previous post I understand that the codes warn of a going throttle body motor. Can this be repaired by simple cleaning and adjusting or do I need to buy a new unit? Also what would be the part number?
