Slammed on brakes now have CEL?
Was going downhill at about 40mph and had to slam on brakes at like 90% force.
CEL came on P0430 bank 2 Coincidence? |
cat inefficiency bank 2..hhmm..it wouldn't hurt to take a look at the rear O2 sensor..check connector(s)

I finally got around to checking into this and I think I found the culprit...

You don't even have to take off the cats. Just buff down the surface on the flanges and take the rust off all the way around. Then while it is cold, patch the holes with VersaChem Muffler Weld(repair and sealer). Works like a champ, though you have to let it set up for 12 hours or so. I patched mine after I got a 420 code, and it fixed it right up. Can of it costs a whole $7 or so.
Then again, you could dremel the bolt heads off, separate the flanges, install new gaskets and bolts/nuts and enjoy another 25 years of reliable quiet Lexus . . . Colin |
