did you put e85 in the tank?
maybe you should reset adaptations?
only remap now.allready investigated a little and at idle its lean,the more rpm the less correction needed.
sold Cobb AP...maybe carīs battery connection off for 1 night does reset adaptations?
i put allways 98octane to tank.

P0174 and googled...says all over again most possible reason "vacuum line" leak
or maf, but think N54 doesnt have maf..only TMAP or something.even mechanic says very possible vacuum leak,because the sensor which report this error is before the precats.
