    Make sure cyl 5 spark plug wire isn't touching the front O2 sensor wire.
    Irridium spark plugs last 100k mi and work just as well as copper. Copper is a waste on N/A and only lasts 15k mi. Don't use Platinum.
    Use 195* tstat unless you can thoroughly explain why not; 99.9% don't need a lower temp.
    Almost any oil filter, ever, is of higher quality than ACDelco. Spend $6+.

    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.
