I was thinking of purchasing wheel and tire combo from www.wheelsnext.com. Anyone have comments on them? Homer

Hello Guys, I've got an 94 LS 400 with 114,000 miles on it. Until this last week, it's been mainly trouble free. I went out of town and came home to start the car and everything seemed fine. UNTIL i drove it. I noticed a MAJOR power loss and the engine just would not rev. After about 5 minutes of this I looked under the car and found the cats were glowing red. I've since changed the cats thinking it was the cats that were bad, the problem still exsist. My buddy who is a tech at the local Lexus dealership was baffled as well. He says that it could be the resonator that's clogged and backing everything up to the cats. What do you guys think? Any input would be greatly appreciated! TIA! Homer
