kountryboytexas Posted September 30, 2008 Share Posted September 30, 2008 Hello everyone, I have a problem with my 92 lexus ls 400. The engine started loosing power and the exhaust got real hot. I replaced all the converters 3 of them. Problem still the same, no power and exhaust is real hot. From the converters back to the mufflers. Can it be the o2 sensors causing this :( Quote Link to comment Share on other sites More sharing options...
93ls400walt Posted October 3, 2008 Share Posted October 3, 2008 I'd look at the coils. The driver side coil seems to go out first. Quote Link to comment Share on other sites More sharing options...
