Message	what I've found TWC = "three way catalyst". Just curious if someone has more specific experience. I did recently install SZ high flow CAT pipes and in the process had to replace the left side rear O2 sensor. From what I've read, it may be the pre-cat. I cleared the code and we'll see if it returns. I am running injector cleaner in the tank right now. 1996 TT #61 of 300
