no those codes went away after replacing the intake manifold gasket. but here are the nine codes that the truck is throwing at me P0466, P1000, P0135, P0141, P0153, P0155, P0161, P2197, P0403
There's a number of electrical connections that need un-clipped when removing the intake manifold to replace those o-rings. Have you checked all connections, as well as the nearby vacuum lines? With it throwing so many codes currently, I'm thinking something just wasn't hooked up properly and was overlooked. I've actually been fighting the same exact codes you started off with and keep coming up empty handed with what I've tried. Time to start throwing parts at mine I suppose. lol.
ya i was thinking the same thing but im going to have to wait till gets a little warn here. but ill keep you guys posted on what im doing.
