As some of you know, I am going through all the elctrical probs with my car, and making progress! I've run new grounds at the battery, engine, and CPU, and an additional wire at the alternator...
Anyways, I wasn't getting a reading from my O2 sensor, and I was getting a code from my pressure sensor. I took out the old O2 sensor, and it was rattling around, and BENT!!(??) The media inside was fractured. ANyways, replaced it, then tried hooking the boost sensor up again, fingers crossed... No codes!! The ECU is getting proper signals now!

It's much better behaved while driving normally now!!

Anyways, I can also check the o2 sensor output while driving, and it's definately still running rich.

At idle- .95V
Accel 1/2 throttle .91V
Criuse- .90
Full throttle- Dead on .87, right to redline- Good!
Hmm... I guess the S-AFC that I'm getting will correct that.
The idle is really rich right?

HAILERS

At cruise you seem to be way too rich. If we're talking about in fifth gear doing 60mph, then you should be seeing the meter jumping around on either side of .40 v. Doing it rapidly also. Like you'll see for a moment .65 and immediatly after that a reading like .35v and this pattern will be repeated rapidly. Not those figures, but figures on either side of .4volts. And not just fifth gear, I just used that as an example. Say forth gear doing 30 or 40 or 50or 20 etc. The .8 or.9 at idle seems to be normal for cars that do not have the acv and airpump to supply port air at idle to mix with the exaust(I know I stated that just a bit irregular). Sounds like the *closed Loop* part is not working. You seem to be making good progress though. Try driving at 60 in fifth and look again at the 02 sensor output and see if its jumping around stoich or not.
