Installed OFH but...
I just got a P0171, P2097 and a P219A code. And I have searched it up. It says I'm running to lean, but I can smell gas. Like I've been driving a gokart. ps: running catless headers and catless FP w/ stg2 uel oct91. So I think that's the gas smell.
I tried clearing the code with the OFT, but it came back after a while. I wouldn't know how to check for leaks, or check if my MAF is dirty, check my o2 sensors or how to fix such things. Any help would be greatly appreciated. Last edited by ShibaYuki; 09-13-2015 at 12:40 AM. |

Are you already running the UEL tune?
P0171 is too lean on bank 1 P2097 is too rich on bank 1 P219A is a/f ratio imbalance on bank 1 These cars only have one bank for O2 sensors, so you can ignore the bank 1 part. If this wasn't happening before the header, it's pretty safe to rule out the MAF. Are you getting all three codes back, or just the lean code? Did you install the header, or have a shop do it? If it was done at a shop, I'd go back and ask them to check for leaks and to make sure both O2 sensors are plugged in and in the right locations.

Well the car probably is in limp mode, so it's safe to drive it to the next place provided you don't rev it high

The reason you smell gas is because you're catless.

I'm getting the codes back so it's either it has a leak, or O2 sensors are bad? Would reusing the old OEM gaskets be the cause of this when I installed the OFH? |

Could be. You should use new gaskets. Are the 02 sensors plugged in correctly (black to black/grey to grey. In the right bungs)?

I may have to take off work tomorrow just to get this issue fixed. I also have to buy new gaskets at the dealership tomorrow. I will check if my o2 sensors are plugged in the right place. From what I saw earlier, the black is on black, and grey is on grey. I'm not sure about the bungs. I can't see them.

How would I know if that is where the actual leak is? And how would I be able to fix this? |

Voltage too low wouldn't be from a leak, that sounds like either they plugged the O2's into the wrong plugs (swapped), or something was damaged.

Thanks, I'll check out the plugs right now. But I really doubt it was swapped by accident. I believe it's a leak at the o2 sensors. Or maybe it's damage. Does that mean I have to buy new sensors?

Yup, if they were damaged or cross threaded I think the only option is to replace them.
