The live data on the o2 sensors seem to prove the cats are bad. The upstream fluctuates like it should but the downsream is not staying steady. Its acting like the upstream o2 sensor. I still dont know about the vvt code. Does the 3.0 have the same problems as the v8 with the timing chain and tensions? I have alot of money in this car and i hate to give up on it but if its going to cost more i might have to call it quits. I thought about putting new cats on it but not sure whats going on with the vvt.
