Here is the stats:
2008 GT with American Thunder Flowmasters
Runs good, no engine light came on.
Added a BBK CAI that needs no tune.....Hmmmmm!
Drove about 100 miles today and the Engine light lit up on the dash.
I have an old scan guage and it showed a P0174 and P0171
Here is what they are:
174 (M) Oxygen sensor was slow in switching Single, Right or Rear HO2S
171 (M) Oxygen sensor not switching - system was at adaptive limits - Single, Right or Rear HO2S - l

I take it I am running to lean and need a tuner? Anybody else run into this? Also, the breather tube is pulled pretty tight. Any idea on where to buy a longer one?

Thanks everyone in advance for your help!

Yes, a tuner is your best friend here.

A Predator or Trinity will allow you to richen your MAF curve to increase fueling and eliminate those codes, while also adding a bit of power at the same time!

 

Thanks Mike.
Appreciate your response!
