I've got a P0133 code now. Certainly related to my LT's I guess.

First off, is there a list of codes somewhere? This would be nice to bookmark or sticky.

I drove for 2-3 weeks with LT's on my 93 Race tune an never had a code. I tried out 93 torque today, and got this code. I'm surprised Bama gave me 1 tune that liked the LT's and one tune that did not.

Sticky list of codes?

Has anyone here been successful in fixing a P0133 code? Doug @ bama says I have the right tune, although I need to ask him directly if I've got the max O2 delay programmed in. I've read I should tighten down my header bolts again to make sure there's no exhaust leak. I've also read I should swap the driver & passenger side sensors to see if the error code swaps banks, which would indicate a faulty sensor. I have looked at my CAI & MAF connections and don't see anything loose.

I'd like to hear from anybody that has been able to fix their P0133 - what did you do?


...fingers crossed that re-tightening header bolts will help me.

Just got both of these today, about a month after I put my LT's in. It's reset, and I'll see how long before it comes back. From what I read, it's nothing to worry about. I may try swapping the sensors to see if it does the same thing.

This week I put in a new O2 sensor for the one I was getting a code on (car was supposed to already be tuned for LT's). Light hasn't come back on.

HOWEVER - I find it highly suspicious that my O2s would suddenly go bad within weeks of getting LT's. I am suspicious that my tune is somehow fouling them. Myaybe I'm running way too rich. Maybe the 100% heater duty cycle (on all the time) that Bamachips has me setup on is shortening the life of the heaters in my O2s. I dunno...

the p0133 is for the o2s having a slow response.. i have it too... my tuner keeps changing the tune, its basically got to retard the computer, i went back several time s (its a trial and error kinda thing, different cars respond differently) i just gave up and drive with the light on. just clear the code with your tuner, itll be back within an hour or two of driving, and when u need it inspected just get it retuned and have your tuner play with the comp
