Hi all...new here. Thought I'd try out a different smaller forum. Too many clowns and wannabe's on some of the other larger sites. Gets too complicated trying to sort through the BS to get some knowledgable information.
So, here is my delema:
I have installed the preditor performance tune and slightly advanced the timing. Im very happy with the tuner. Have not had any of the issues many talk about. Car runs like a friggin cheetah! So, the other day I'm in real time just for fun. Everything is right on the money as far as LTFT's (+2/-1.78)....and all 0.00 at WOT.
Problem: 3 out of 4 02s are running aprox. 880-920 mv...thats good...But, 1
is at 58mv at idle and only gets to 300 at WOT. Then it will occasionally jump to around 800 for a moment, then drop back in the 100's. :willy:
Wadda ya think? Bad 02 sensor? I get no SES or codes of any type.

Thx,
Bill

While I'm no expert, it sounds like a bad 02 to me....should all be the same or very close.. :cheers

Cool, it didn't throw a code probably because it was still within "spec", it was only a matter of time...... :willy:
