Any help with the following code would be helpful.

<!--[if gte mso 9]><xml> <o:OfficeDocumentSettings> <o:AllowPNG/> </o:OfficeDocumentSettings> </xml><![endif]--> B0821
System too rich at idle bank 1
Value below lower limit value

background, recently changed exhaust and I had boost leak, boost leak was fixed then this code popped up.

I just cleared it do I just see if it comes back? If it does, what could it be?

TIA
Carmine

It seems from a couple of your posts you've had several CELs since changing your exhaust..
Have you done any other mods at that time? What exhaust did you go with? Just curious as I'm about to install an exhaust myself..

 

To be fair, it turns out that when I went to reconnect the inter-coolers, the piping didn't quite mate properly so I got boost leak. These accounted for the previous CEL, B1510 and B1095 (IIRC).

I put in a Power Agency exhaust with sport cats. I think my novice install was more at fault. However< i now believe I've upset the fine balance of the OEM setup and dealing with the repercussions.

No other mods, taking small steps just in case stuff like this happens and you just can't pinpoint a culprit.
