maf code plus lean and rich.
i recently switched over to E-85 and when i was tuning the first night with my tuner, the car was flaweless. it learned down a day later and has since been all whacky.
symptoms. completely fine until it randomly lurches during acceleration and then the AFR goes rich, 12-10 and this is all while cruising. it stays like that for about 20 seconds and levels back out. After more driving it lurches again and then throws the codes: p0101 p0121 and p1101. It doesn't go into limp mode but lacks power. i have an interceptor so i delete the codes and the car acts fine until it lurches again. I informed my tuner and he said until he can look at it that i clean the MAF, sensor above the SC and the sensor about the main coolant hose. i did so and nothing changed.
any ideas what could be causing the issue?
