codes 2AAF, 29DC, 29CF

blackbeast06 · 08-23-2012, 10:09 AM

So I tried E85 on jb4 map 5 and after 20 miles of driving I got on it hard in 3rd gear. At the top of the rpm band I hit a brick wall and car went into limp mode. Got home read the codes and the three appeared. 29CF is misfire cyclinder 3 and the other 2 are related to fuel pump and cylinder shut off, which I feel like will always pop up with a misfire. Replaced the ignition coil for cyclinder 3 and back to normal. Just wanted to give a reference for anyone else who gets these codes in the future.

I have these exact fault codes and wondering if you ever figured it out.

Thanks,
Kaz
