fragman Posted March 2, 2008 Share Posted March 2, 2008 hello all, ive owned a 92' LS400 for about two years now. Suddenly today within 5 minutes, the car started to spudder at about 2000rpm and white smoke from under mid car started to come out. Later when i got home, i reved it to about 2500 rpm in the drive way. No way near the usual in terms of speed at which it reached rpms. after i shut it down and looked under the car, the exhaust were glowing a bright red-orange!! it was running at low rpms in neuteral for about 2 minutes!!. this is my dads car that he uses to get to work so do you guys have any suggestions?? thanks in advance, Steve Quote Link to comment Share on other sites More sharing options...
TexasLexus94 Posted March 2, 2008 Share Posted March 2, 2008 I had a similar problem with my 94LS recently, and it was caused by Mr. Stupid (me) incorrectly installing a wire to the lower ignition coil. I had broken the clamp that holds it in place. When it loosened, I could drive it home, but at half speed. The cats were red hot. Doubt if this is your problem, but you never know. Best of luck....
