It all depends on what the issue is. Do you have all 4 O2 sensors installed? What are the codes your getting? My LG's had only 2 bungs and the installer did not edit out the other two so I threw a code once a day. I bought a set of O2 sims and that corrected the problem. If all four are installed then that would be a different issue. Certain LT's don't produce the right amout of heat for the rear O2's and that can cause problems.
