right & left bank codes
Problem started about two weeks ago. Miss in engine identified as P1277 and then P1266 codes. Took apart all harness connections and cleaned with chemical cleaner. Took care of #7. Now have P1316 mostly, but also get left or right bank malfunction, or low contribution on banks of cylinders. Also have a P0476 and yesterday died with cps (New one put on afterwards).
Am thinking corrosion on connections, bad idm. Have new valve cover gaskets & under cover wires on the way, along with new exhaust pressure sensor and will do tube cleaning. Any ideas?
