Hate to bring back old threads but I could really use the help on this. Done a bit of searching obviously but couldn't really find the answer for my specific situation.
I have a '97 2.7 4 x 4 with 235k on it..
Last Friday I had a Magnaflow
18" oval installed with 2.25" custom stainless pipes from the cat, straight back to the muffler, then up and over the axle, side exit. She felt great over the weekend, no problems but this morning I threw a PO420!! Had my buddy's shop clear the CEL but I really want to fix the problem.
My exhaust guy didnt say anything about the condition of the o2 sensor he welded back on so I don't think its that, and the existing cat seems to be in perfectly good shape. He did say however that there's a crack in the manifold that he can't find (doesnt sound that good though) and there is also a slight leak at the gasket upstream of the Cat.
I'm looking into headers, but til the coin is there its not gonna happen. and when the time comes I'l prob replace them as well as the cat (already have a brand new magnaflow high flow cat).
Any advice/recommendations for the time being to get rid of the CEL??
Will the 02 sim from URD
work on my truck? seems like its only for 3.4l..
