Dumped Antifreeze into Wiring Harness

[carfreek]

Title says it all-Dumped a pint or so directly onto/into wiring harness. Car runs, but there is no O2 feedback like normal, and Vfs never modify, no matter how lean or rich I adjust fuel at AFPR, or with SAFC. Car has 2 operating modes. #1-Start engine. AFRs start and stay high-16.1-16.5. No o2 feedback,VF reads at 0, will run like this for 5 minutes or an hour. #2-2nd or 3rd key hit after starting, 14.5 idle, 13.5 cruise, VF cycles around 2.5, but never goes to 1.25 or 3.75, no 02 feedback. Any suggestions as to which circuit is shorting out in wiring? ECU is throwing no codes, and is not learning at all. ECU has been swapped, and car exhibits same symptoms. TIA, Mike

UPDATE-2 bad connections in harness. 1, obviously, was o2 sensor wire. Second was ground join for EFI Temp switch. Obvious in retrospect. Antifreeze contributed to second, but not first. So, I must have pulled on O2 wire while doing work on heater valve. Live and learn.
