I sent my ECM back to John at Speartech and had him remove the DOD/AFM function that was giving me problems (as some may have noticed on my other thread). The motor now runs 100X better and is super smooth. All codes are gone except for a bank 1 and 2 lean code. I was wondering if someone might know if this is because my crankcase ventilation tube is on the filter side of the MAF rather than the manifold side. Does it matter?
