Again, the only explanation I can make for your continued problems is a faulty DME sensor heater driver.
Ah thats what i thought. If i got this right, my fuel trims are not maxed out(Short term fuel trims, STFT) Bank 2 sits at 0.0, AFRs are high when monitoring though MHD, bank 1 is working fine, by looking at logs.
Gonna have the car checked out next week, someone with more knowledge than i have and the right tools, hopefully its not the DME..
