I just installed my turbonetics turbo kit and it is running great. I still have a cel though and I know there is not supposed to be. I have the spacer for the o2 sensor installed and when I checked the code that's what it read was wrong. Anyone have any suggestions? I also have an AEM wideband hooked up and under acceleration it really seems to bounce around alot. Ive never ridden in another car with a wideband and I was wondering what to expect. Ive only been in cars with narrowband gauges. Other than that install went great and it seems to run great.

 

Just driving around the AEM is going to bounce around because its going in and out of open and closed loops. Whats it say at WOT?

Something I did when installing mine....I forgot to plug the 2nd o2 sensor back in. Causing nothing more then a CEL till I remember to plug it back up. Could be that simple. What was the code? Like the number?

 

Did you put the extender on the O2 sensor on the Spipe or downpipe?

 

The extender is on the s-pipe. At WOT the wideband reads about 12.1-12.7. Somewhere in that range. I checked to make sure the second o2 sensor is plugged in and it is. Im not sure about the code number but it said something like heater curcuit low on 2nd o2 sensor. I can get the exact code if that would help.

 

that means the ECU thinks the second O2 is not connected . When the O2 gets hot it sends that info to the ECU.

 

Might try resetting the ECU and see if it comes back if you haven't already. Keep in mind that O2 sensors can be sensitive. If it was dropped or had an excess amount of oil or something else on it, it could be failed for real.

 

me and my check engine light have become one

 

12.anything are WAY too lean for the stock tune. Something is wrong. I never went above 11.4 afr with the base tune from turbonetcis.

 

12 range is what what my aem is reading at also . Are u sure thats not the stock tune.??? i have no cels. Btw , to the person that has a cel, did u plug in the supplied turobnetics anti fouler on the secondary o2 sensor, if u put that in and reset the ecu u should be reading now cels

 

For a stock motor I wouldnt feel right driving the car with the AFR's above 11.7ish. I think I'm like a 11.1 -11.2 right now.

 

possiblyt could be the weather done here.... it gets warrrm then next day HOOOOT, and possibly elevation.
