So my check engine light came on today and went to get the codes read:

Rich air/fuel ratio
Air lead near rear h02
faulty fuel control

Please help on whats going wrong and what I need to do to fix this?

THANKS!

 

Most likely a bad 02 sensor or bad maf. You need to get the actual code numbers.

 

Code: p0422

 

16806
P0422
Main Catalyst,Bank1 Below Threshold
That means you have a bad cat converter mate. It happens. You can still check your fuel trims on data block 32 via the vag com, but if thats your only code its probably just a bad cat caused from previous misfires. I would check your misfire counter (data block 16) and see if there are a lot of them. However having a plugged cat can cause misfires.....

Nice wheels by the way.

 

Thanks for all the help! I appreciate it. So would you suggest on getting an oem cat, or strait pipe it instead?

 

You can also get an HFC (high flow cat) which is much cheaper than the dealers $600 price tag, and you won't have to deal with the check engine light.

 

i got mine from ebay...high flow cat.... $150
