Message	I barely remember doing the delete so I can't remember capping the line by the CC but almost sure I did based on the writeup. But wouldn't a vacuum leak just cause it to run lean? I'll have to check but I think the AVC-R piggybacks the PS O2 signal. I would think a vacuum leak on the DS would raise the AF ratio on the PS- opposite of what I'm seeing. I may have to pull the fascia to double check. -------------------------------------------------------------- ---------------------- Conversation between my sister and my wife (shortly before we got married): Wife: "You know, sometimes I think he loves that Z more than he does me." Sister: "He probably does, and as long as you're okay with that, everything will be fine."
