    Some Help please Code 29E1 and 2FBE

    2008 e92, been running strong on a mixture of 30% e85 and 70% e93octane on map 5, JB4. This morning on the way to work, call keep on sputtering than stall. So I headed back home and pull the code, I have two code:
    29E1 Fuel mixture control 2
    2FBE Fuel pressure after motor stop

    The car is out of warranty and it's currently at 49k mile. I want to throw it back into stock to see if it's okay, but since I have that 30% of e85, would stock give me any trouble? any recommendation to resolve these two code? Thanks

    I would go to the gas station and fill it up with premium to reduce the concentration of ethanol and see what happens, though I don't think 30% e85 is excessive. That's 33% total ethanol by volume based on the E85 actually being 85% ethanol and the 93 octane having 10% ethanol. So it's ~3 times more ethanol than with 93 octane alone.
    Eppur si muove.

    pull JB4 out, fill another 4gal of 93octane and put into the tanks, which makes the car full. Its alive again and stable. might be a sign of sparkplugs going out, i'll try to used all the gas and refill couple of times and try JB4 again with new plugs and see how it goes.
