I've struggled to get my Honda to pass emissions. I've taken 3 times and it failed. I got underneath and used metal patch and followed all directions. There were quite of few exhaust leaks. I'm still getting a PO171 code. I just removed the MAF sensor and cleaned it. I'm just waiting for it to dry before resembling everything. The oxygen sensors have been changed 2 times. I'm looking at all the possibilities on other things it could be?
Thanks in Advance😊 {black}:razz:
I haven’t dealt with this problem specifically in person. But just reading up on the code, it suggests there may be a vacuum leak, and/or the fuel delivery system isn’t working properly (too lean).
I know! I've been checking everything. Now that code went away and now I have a PO137 and 1133😠
This is just a wild guess based on the codes. Try cleaning the fuel injection system. And if that doesn’t work, check the fuel pump. Like I said, this is just a wild guess, so a person that knows what they are doing might have a different solution.
Is there something I can put in to clean the fuel injection or do I have to physically take it apart {black}:scared:
@Roxiee try a can of BG cleaner. Pour it in an empty tank, fill it up and drive on highway for a good amount of time. Hopefully it helps.
Thank you😊Well I'm at a half tank of gas!
