codes being thrown after tuning...
 

I just recently had my car tuned and rechecked again after that and my rear o2's are still saying no activaty and the smog pump as well when they have already been deleted out. It also throws a throttle position sensor code as well. Any help on what this could be?

anybody ever had this problem?

Please post all the mods on your car, kinda hard to help you without any real info...

i am throwing front o2 codes after having the rears deleted. i went and bought corvette o2s and the damn light came on again. this kinda sucks. hope you get it figured out.

Yeah didnt think about that. Here is a list of that will alter the tune.

TSP 233/239 .603/.600 112+2
Pacesetter longtubes
TSP Trueduals
SLP lid
FTRA
RPM Tune
That should be the only mods that would make a difference on the tune.

I'm having the same problem. I just replaced my precat 02s with bosch 13111 o2s, my rear o2s have been deleted so not to throw codes. I have a 98 WS6 A4 Conv with Borla T304 stainless exhaust & 160 degree thermostat. I bought these o2s cause everyone in these forums are raving about them. If someone could help out I'd appreciate it too. :confused:

if you had your rear 02's deleted and then your front 02's trigger...someone has done something wrong. *possibly could be wrong but i doubt it. Don't always assume your 02s took a shit. everyone told me 'oh your 02s took a shit, oh the new 02s you bought took a shit too' thats a load of crap in my case. looking at the logs and looking at evertyhing it came to be my injectors..but back to this story.....

i bet a tuner did something wrong
