check engine light code 29e1

sjthegreat1 · 06-28-2013, 03:03 AM

hey guys I got a 29e1 code after I just started my car! it does feel ok but seems like its vibrating a bit more. I understand this code can be anything from injectors to coils to o2s but I want to know where should I start. I do have jb4 and did change sparks and also did sandblasting myself. any help will be appreciated thanks!

I get this code occasionally, sometimes accompanied by a CEL and sometimes not. Also it is sometimes associated with a "system too lean" code. but car runs/idles/starts great and data logging on my cobb shows perfect AFRs and trims...??? Started when I ran E85 mix a few times but then persisted long after I switched back to full 93. so i basically just ignore it.

I would look for air getting in the system, check the O2, and finally the injectors. My problem was the injectors.

In my case BMW smoke tested intake, crankcase and exhaust and found no issues.

I already checked o2s wih inpa and they are within spec! ill try to get a smoke test done this week! I think I got the injector recall done on my car. however one injector seems like it wasn't replaced because it has the old number on it. I might have to replace that one and go from there!
