What could cause my car to throw all of these CELs? Its impossible for all of my O2 sensors to have gone bad at the same time, especially since one of them is only a few months old (replaced when I changed midpipe). Not only that, but also all 3 of these other codes aswell...Really need some advice on this, if anyone has any ideas what could cause all of these codes please give me any advice you can, I'd love to try to fix this cheaply on my own...before I take it to a mechanic and pay $$$.

my threw that manufacturer code, it was the vapor canister doesnt hurt anything just another save the planet device, sensor 2s are the rear o2 sensors which doenst mean crap , only one i would worry about is the front oxygen sensors tune out the rest of those codes with a handheld

when i had my car dyno tuned i had them turn off ALL my emission codes except my front oxygen sensors so i know if i run lean

What about the purge valve? I'd really prefer to find out what the actual problem is and fix it. I have cats so theres no reasonf or me to be getting the rear O2 sensor codes, nor should I be getting any of these codes. There has to be one problem causing all of these codes.

If your not getting a lean or rich code none of those codes really affect anytihng but emissions pretty sure

it does seem strange that all o2 sensors would go at same time , along with other things as well

It's been causing my car to die randomly while coming to a stop though (not my IAC, I already cleaned that out). And actually...sometimes after I get on it atm I can smell it like its a bit rich.

try disconnecting ur battery termnials for a few minutes to clear the codes, and see if they come back on

Already did this, when I cleaned the IAC. Also...its impossible for all 4 O2s to go at the same time like this. One of them is only a few months old, I replaced it when I did my midpipe install.

Anyone got any ideas on this? Please?
