Anyone had problems with their o2 sensors repeatedly throwing a code? Just had it in at the shop yesterday and they replaced one. Not even 50 miles later it's back on. Only mods I have done are a Cold air inductions CAI, stage 2 Bo White TB, phastek scoop kit and a Borla cat-back system. Is she breathing to well for ththe o2's? Thanks guys!

Almost impossible to diagnose based on "threw a code" we need the dtc to help figure it out. Also, no such thing as "breathing too well" for an O2.

O2 sensors measure the amount of oxygen in the exhaust . Scan it and see what the code is , your car has 2 upstream O2's and 2 down stream O2's . Unplug each one and check to see if you have a bad connection and plug them back in . Your mods should not have caused the problem .
