I've got an 03 LS and for about a year now I've kept getting the code P0133, it goes away on its own sometimes but never fails to eventually come back. I have replaced all four O2 sensors and cleaned the fuel injectors, and the car runs fine...
Anyone have any ideas what else this could be?
The tune definitely makes the LS even more fun to drive . I think the purchase was worth it although I didn't notice a huge improvement in performance, if I were to guess it gave no more than 20 more hp. Still a great purchase because it makes the car feel so much better. First of all you can...
I recently bought a K&N air filter and SCT tune from Torrie. From what I can tell the 0-60 is just above 6 seconds. I was getting 6.2-6.4 seconds with 3 grown men in the car, and of course with just a timer. Good luck!
