Default 29E0 - Fuel Mixture Control - 11-15-2017, 09:42 PM

Hey guys, I've been dealing with a lot of issues with this car and quite frankly I just want the to be over. With that being said, the issue at hand is this code. 29E0 - Fuel Mixture Control. I've done a Google search that got me nowhere and I'm wondering if anybody has an cure for this code. The car is a 2010 E92 335. My symptoms are a rough idle, lack of power, and it's shut off twice. The rough idle feels like it's about to misfire but never does. What I've changed recently is, oil, OFHG, valve cover gasket, water pump, coolant, all 6 spark plugs, bank 1 pre *** o2 sensor, and cylinder 5 coil. Any info helps.

Thanks in advance.

This code can be pesky & hard to track down.

When is the idle rough? On cold start, or all the time,

It's rough all the time. No matter if it's cold or fully warmed up.

If you are getting 29E0 and not getting 29E1, then that is generally a hardware issue as Dave stated. Injector, O2 sensor, etc. Did you reset adaptions after replacing the O2 sensor?
