been a not fun couple weeks.
most notably, 2 nights ago the jeep finally decided it was time I deal with the right front corner, and started shaking like crazy.
I hate living in a Rust Belt state, makes working on stuff a disaster.
finally got the axle and shaft out; they were stuck together...
necro thread!
seriously though, what do you mean by "stable" and "perform better."
qualitative questions have no answers. quantitative ones, however, do.
wait until the backing plates fail.
Also, think I finally have the answer with my weirdness.
tried swapping out B2S1... didn't solve the problem.
finally started looking at a different set of O2 parameters (O2 Volts (0-1), instead of O2 Sensor Volts), and can now see that B2S2 is biased lean by...
Well the Jeep continues to be a bit of a pain in the ass lately. I'm not sure yet, but changing the upstream sensor has apparently cured the reporting lean condition. When I data log that sensor it appeared to be switching appropriately. That was a week ago. Now, I took it out for a drive today...
well I got B2S1 O2 replaced.
old one was siezed and buggered up the threads, but I got the "replacement" installed regardless.
going to need to buy an O2 tap I guess, for future use.
scan tool is making happy graphs now, although I did briefly get a P0157 Code: Oxygen Sensor Circuit Low Voltage...
so the other night the right rear suddenly started making a death noise.
turns out the sole rivet still holding the backing plate on, let go.
parking brake shoes are destroyed.
I got the plate booger welded to the housing for now, so at least no more death howling.
I'm gonna need to replace...
P2098 Post Catalyst Fuel Trim System Too Lean (Bank 2)
either I have one hell of a tiny and consistent leak into the exhaust, or I have a possibly failing/failed sensor.
*sigh*
been driving it all week, because reasons, and now it's tossing P2098 periodically.
going to plug the autel in tomorrow and see if I can datalog something useful.
I'd go with 04->04, and it'll be as had as how much crap you do or don't move over.
I wouldn't worry about the various modules, as you'll need to re-vin the PCM anyways, so you're looking at needing a high-er end diagnostic tool to do that.
diff ratios, I wouldn't worry about for the moment...
