Do things codes separately or together give an idea of the overall problem. P0174, P29E1, P29ED. Car has Cobb stg2 aggressive. DP's and Midpipes, DCI.

29E1 = fuel mixture control 2
29ED = mixture adaption, lower speed range

I can't find the other one, but if I were you, I would log with the AP and see what is going on with your car.

Log it, you'll see if anything is out of whack..FWIW I got a P29E1 after using too aggressive an E85 mixture not long ago, cleared the code the next time I filled up with 93 pump, and has yet to return. The car drove fine with the code, though I had cleared it and filled back up within 48 hours of pulling it from Cobb.

I am running E85 and this only came up when I was below a quarter if a tank so today on the way home ill fill up with 93 and see if it takes care of the problem. Thanks.
