Check engine light, P0133? I have gotten this code twice now. I cleared it once and it came back about 30 miles later. Its O2 Circuit Slow Response. What could be the problem? I have LTs, and ORY. I replaced the O2 Sensors awhile ago, maybe 1000 miles. What else could it be?

CHECK it in engine DTC
HP tuning
or talk to your tuner if someone has tuned the car
if you run the scanner and the sensors are working fine ,, i dont know ,, but just ask someone to scan the car for u

do a search this is a ongoing problem with many incuding me..
It has to do with long tubes not allowing the sensors to heat up correctly If i understand right..
LT headers as a rule run cooler than a stock setup, where the o2s are placed close to the engine.
Ive heard where cats help this issue by building up some heat.. Im considering going back to high flow cats because I have no mufflers and its too loud and I feel like I might kill two birds with one stone.

Could be an exhaust leak on the driver's side. You could try changing the sensors from one side to the other. This should help indicate whether it might be sesor related or a phsyical problem on the driver's side. Read this as well.

If I were to buy the HP tuners or something could I just lean it out a little bit? I have a mail order tune now so Im sure Im running pretty rich. And whenever the light comes on its at low RPMs, maybe just lean it out a little down low?
