Hey all,

Last night I got the traction control + check engine lights come on. I parked at home, turned off the car and tried to turn it on to see what would happen. The engine wouldn't turn.
Plugged in Ecutek and saw P0171 (system too lean bank 1), P117b (DI fuel performance Does not come on DTC), and C1201 (an ABS code with no description).

I've been running ACE 350 + Flex Fuel (Delicious Tuning) + DT E85 tune for about 5 months. Recently been using E85 primarily for past 4 tanks, switched back to premium, then got another E85 tank. The station is a few blocks away and no one ever uses it, so it's convenient.

I noticed my air intake housing was loose so I'm going to try MAF cleaner. Also, heard a noise from the header area some time ago so going to ask the shop to check for a leak.

My research isn't pulling up a good solution other than to try those two things, so if I find out what it is I'll post it here. If you have seen this can you let me know the potential issue?

Thanks
