Hey guys quick question.(2018 mustang Gt JLT CAI, E85 tune). I have been getting code p0003 on my lund tuner. It says heater control circuit. My air fuel ratio is super rich. 8.5-9.8 on idle and doesnt change on WOT. Sometimes it jumps to 10.5. I am currently on E85 and it been on E85 for the past 6 months. I tried cleaning my MAF sensor. I dont know what the problem is. But it seems I am running to rich.
