Finally changed the o2
Finally had a chance today to change out my oxygen sensor. I didn't realize it was going to be that much of a pain. Finally just dropped the exahust except for the connection to the manifolds and that gave me enough room to get the o2 socket in there.
While I was under it I drained the tranny and refilled with Redline MTL, was going to change out the diff oil too, but ran out of time. Through on some new hood shocks too, tired of it almost slamming me in the head.
Hopefully the new o2 sensor will solve the idle and mileage problems. I've been averaging about 15-16mpg an comparing that to the touring which is getting 22 with an auto in it I figured it was time to change it out. If that solves the issues then I'm going to run some G-Tech passes and then put the Mark-D chip in and make a couple more passes.
Anyway, feels good to get a little done on the e34, all I've been working on lately is the e30.

Just did mine (2), the upstream ones, along with cleaning the TB and ICV and tightening a few things, it runs a lot better.
