Is there a way to find out which O2 might be affected?

I'm not quite sure how to do the grounding....could you expound on that a bit? Another thing that happens is that I notice the 'engine' light and 'trac' light go off when accelerating, then re-appear when slowing down. Would I have codes available once I see the lights go on?

I have a 1994 SC400 and love my car. However, I have this continuiing problem with the Engine Light and Trac Off Light. They seem to come on before acceleration, then go off once accelerating. They come on again intermittently. Sometimes while driving, my radio and dashboard lights go off, resetting the clock and feeling like I am losing power. When I stop and turn the key over, nothing happens. Dead in the water. No power, no key dinging, no lights, no nothing. Not even a click when turning the key over. My honey will come rescue me by removing battery cables and re-attaching. Voila! The car starts and everything is good again for about 2 weeks. Replaced the cats. Don't know about the O2's, whether they're ok or not. Haven't checked any codes. Took it to a non-Lexus shop and they couldn't find anything wrong; probably because we reset the computer when we disconnected the battery. He said he did notice the cables weren't tight enough, but I have still seen the check engine light come on since he tightened them. This seems to be a problem for some of the folks out there....any ideas? Thanks for your help! Kellie

:cries: Does anyone know if there is a way to manually move the steering wheel down, as it is stuck all the way up? I am a novice working on engines and haven't been working, so a dealer repair is out of the question for now until back to work. Any quick fixes or suggestions? Would be most appreciative.

I lost power one day trying to accelerate onto the freeway and my engine sounded like it was running on only a few cylinders, like a car without a muffler. After a couple of runarounds, found out it was the catalytic converters. Ordered some after market cats and installed all 3 new ones. Found a few chunks of hard rocks? in the main one. Turned it over and whalla! It still sounds the same before we changed the cats. Any suggestions as to what to look for now? It is an SC400, 1994 Lexus, 160,000 miles. Just had it smogged a couple of months ago and it passed with flying colors.
