p0133, p0172, p0420, p1133 All these codes pop up together this is just as of recently nothing has changed on the car it still runs fine sometimes does the rpm jump but rarely stalls and there are no cats on the car so some of them are simple but I don't know why i get alot of codes all the sudden. i keep clearing them and they keep coming back Help

 

cold weather.,... ***** with the tuned cars.... should clear up in a day or so

 

P0133 HO2S Slow Response Sensor 1 ECM, PCM
P0420 Catalyst System Low Efficiency ECM, PCM
P0172 Fuel Trim System Rich ECM, PCM
P1133 HO2S Insufficient Switching Sensor 1 ECM, PCM

I'd get your ECM/PCM checked out. Those are what the codes mean

 

yea but he's in palm beach. You don't see that big of a temperature drop right?

 

i was reading some other posts and its possible that i could have messed up an o2 sensor when i ran some race gas.

 

by what would you mean checked out? i have a custom tune on here should i get it retuned maybe?

 

yea race gas will f---k up your 02 sensor, but I dont think it would throw the rest of the codes would it?

you could try that. I believe you can trouble shoot it on hptuners...

A member in our club had ECM/PCM issues and was thowing similar codes. GM replaced the whole thing (under warranty) which i doubt that they will warranty yours. (sorry )

 

unfortunately i've learned to deal with it.

 

yea, you'd have to get it checked out. Hopefully its just a faulty 02 sensor thats throwing everything off

 

Race gas kills O2 sensors. It burns hotter there for the exhaust is hotter and can melt them and /or damage them in side. Thats prob where your codes are coming from......

 

well you didn't say nothing before about race gas
you need new o2's man.
Done it beofer myself multiple times

 

damnit how much am i looking at? and can i run unleaded race gas or should i get retuned to 93. I had the tuner run extra timing so i only boost when i got the gas.

 

The front O2 should run you about 80 $ and than just put it on your self and run it till it happens again or have it re-tuned for 93.....
