I have a 1997 M3 sedan.

I have long tube headers, removed SAP and have O2 & SAP sims.

After I did the headers I get the following codes:

P1250  
P0173  
P0170  
P1188  
P1189

Any ideas?? I need the CEL off!!

Before the long tubes I have no CELS. Ugh

Are all four O2 sims identical? The front and rears need to show different reading or else it trips codes.

Ok I found out the problem and it is the SAP sim that I got from AA. They refunded my money, and I am now going to make my own SAP SIM.

Does anyone want me to make them a SAP Sim?
