Passanger side cat glowing red hot after TC install
I just got done installing a new torque converter in my car. First test drive it it drove great no problems. few hours later I went to the store and the car was running like *** it was missing really bad and did not want to accellerate.. SES light also started blinking.. When I got out I noticed that my passanger side cat was glowing red!
When I did the TC install I removed the Y-pipe which included the cats.. Any ideas??

A blinking check engine light is usually a misfire indicator. I would assume something wrong on PASS side of the car. Did you have to play with any spark plugs or wires on that side?

Hooked up my EFILive Scan tool and Bank 2 O2 LTFT was pegged at +25%. Bank 1 was hovering right around 0. I did remove the Pass side 02 when I pulled the tranny and a little tranny fliud got on it. I guess it destroyed the 02 sensor.. Went to the auto parts store got a new 02 and the car seems to be running fine now.. Although the left and right LTFT are about +/- 5% apart.. I suspect that may be becasue on is GM and new one is bousch. My only concern is that the cat may have gotten damaged when it got red hot..

Lean will cause your exhaust to run smoking hot, which is exactly what a +25 LTFT means lol. I left a shim washer out from under the needle in the carb on my old MX 4-wheeler and the header would glow at the track because it was so lean. The bitch was AIR cooled too lol.
I would snag 2 Bosch 13111 sensors if I was you. Not sure which kind you're running now.

EFILive's COS3/COS5 allows you to run both hi and lo spark maps in OLSD, so you have all the benefits/protections.

Glad you fixed it... Was it an air leak, and where was it...?
Edit: oh, ok, I see it was ATF spilled on the NBO2.
