Fuel pump or other?
Guys,
So I had a thread on 2AAF fault code and everyone clarified what causes this VERY common code for me. I've been getting the 2AAF code for about 6-8 months now. I clear it and it comes back every time. Now I'm also getting 29E1 as well. My car is stock with no tunes or flashes. COBB site says - 29E1 - Fuel mixture control 2 - Typically caused by the wrong O2 sensors in the wrong downpipe or a major exhaust leak. Grey wire loom goes to the back pipe, black wire loom goes to the front pipe. -I've got none of the above issues. Multiple Forums say - 29E1 Fuel Mixture Control bank 2 common cause faulty fuel injector, ignition coil or spark plug. -I did the plugs 2,000 ago. -All coils 25,000 ago. Any folks who have experienced this please chime in. Of coarse any help in general would be awesome. Thanx yall! |

Just saw this...you may have a bad/leaky injector.
If it were me I'd pull my plugs and see how they look. If any are wet or black that is likely your problem cylinder and you can start swapping components with bank 1 to see if the problem follows. Injectors permanently swapped or replaced must be coded.
