Not uncommon to have 02 problems with LT's. Some people just have the code tuned out. Or widen the parameters that will trigger it. This is just what i've read. What kind of 02's are you running. Some people have good luck with the Bosch 13111's (corvette C5 rears). Do you have 02 extensions or are you running a long 02? These are some of the questions you will be asked. Also, if you search you will get a mindblasting amount of info on this issue. I know I have.
