It has been about 2 months, so I decided to update.

I have had 3 LH modes in all this time (it happens, but about once every other week). A restart takes it away.

I still have the Check Engine Light, I know, the O2 sensor (still cannot get it out, will give it another shot this weekend).

These are the codes I am getting after 2K miles.

LH-SFI Module (N3/1) Socket 4:
22 - O2S 1 heater, open/short circuit

ABS w/ASR Control module (N30/1) Socket 6:
30 - CAN data line to EA/CC/ISC module (N4/1)

EA/CC/ISC Module (N4/1) Socket 7:
6 - Starter lock-out/backup lamp switch (S16/3)

14 - Closed throttle position contact switch (S29/3)

Base Module (N16/1) Socket 8:
10 - Base module (N16/1) voltage supply output fuse F2 open circuit
11 - Base module (N16/1) voltage supply output fuse F3 open circuit
12 - Base module (N16/1) voltage supply output fuse F1 open circuit
13 - Base module (N16/1) voltage supply output fuse F4 open circuit

Ignition Control Module (N1/3) Socket 17:
1 - No Faults in System

Diagnostic Module (N59) Socket 19:
6 - Idle speed control inoperative

12 - Heated oxygen sensor heater, open/short circuit

SRS Control module (N2/2) Socket 30:
9 - SRS warning lamp (A1e15) or insufficient time to read out the DTC memory or erase DTCs

Somewhat different from the last time. I replaced the brake line and the brake light switch.

Socket 8 codes are BS, as all the fuses are OK.

I will erase all codes and drive for a week to see what comes back. I know for sure the O2 will be back (22 on socket 4 and 12 on 19)

The only thing to replace is the NSS, but I will not do it unless LH becomes a REAL problem (more than once a day).
