I replaced my intake elbow trying to sort out some codes (P0172 and P0175, rich condition codes).



My old elbow was in good shape so I dont think it was.the problem. I didnt find anything worrying in the intake except that the DISA was a little bit loose. I think I'll just buy the GAS rebuild kit to head off that problem.



I also popped the vacuum manifold off to check for sludge. I moved last year and our new town gets lots of snow, and my place of work is very close to home, so it gets driven for a lot of short trips in cold weather. I did the CCV two years ago but have spotted sludge under the oil cap. Fortunately I saw very little in the vacuum hoses and manifold, so that makes me feel a little better.



Next up is the cooling system overhaul, preparing for a long trailer season this year.
