BEEFY

I Smile when Gasoline Can Freeze
Started working on the wife's frontier last night. Pulled the codes, p1148, p1168, p0135, p0155, p0154. These all seam to be from the up stream O2 sensors. The truck has doug thorly headers and no secondary cats. I was going to order new O2 sensor then I noticed that there were cel eliminators installed in the headers for the up stream sensors and no cel eliminators on the down stream sensors. That should be the other way around, shouldnt it?

That's correct.

Up streams need the full exhaust gasses to know what the engine is doing. The down stream need the CEL's to trick the computer into thinking there is a working cat.

How are things going otherwise?


They are good man, things are good at home - getting the place fixed up nicely. Yard is still a disaster, but the inside is coming along. The MX was just paid off like, two weeks ago - so that is awesome too. Putting her back together and shopping for Coil Overs and Leafs. Finally going to get back to the trails.
