A friend of mine bought a 94 ls400 recently, while going home one night from work he heard a a noise, a few minutes later his car started runing like . He took it to the lexus dealership and dropped it off, the next morning they told him the catalitic converters blew, and clogged the whle system as you all know the mafia wanted to charge him 8000.00 for just the parts!!! I got the info off the site to get the converters delivered for 550.00 for all three, well the mechanic that he new installed the converters, and the car still runs like any one have any clues to what is still wrong :chairshot:
