Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Air fuel, O2 readings off, causing weird acceleration



Okay I will. I checked every place that has a vacuum I could think of today with no avail. I did find I have a small Exhaust leak on the rear crossover. Could this be my issue?
 
I know this is an old thread but I thought I'd throw in my 2cents. DTC P1133 recently popped up on my car after installing my intercooler. I went to Gearchatter & they list rtv contamination of the HO2S as a possible cause of the code. As well as exhaust leaks which I also have lol.
