Does this happen when she's hot, cold, or all the time? I've heard more than one complaint of un-curable rough running/hesitation/you name it when the Iron Duke is cold, which disappears after she warms up. I haven't seen any concrete evidence to support it, but my theory is that the static values which the ECM uses while in open-loop are less than ideal for a moderately worn engine. Once the O2 sensor warms up and the ECM swithes to closed loop, it starts "thinking" and the hesitation & whatnot goes away. |
