right & left bank codes

willflo · #1 (**permalink**) 12-25-2007, 02:41 PM

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?

Oh yes, runs for about two minutes, then dies completely. Wait about five minutes and does the same thing. Pulled it home with the Exploder!

Ok- stupid me. Problem was fixed with new valve cover gaskets and new uvc wires. Cost $150. on e-bay. Took about 3-4 hrs. of time. Truck runs better than ever. Sorry to bother all of you.
