1971 914/4 1.7 with DJET - question is, does this year have the idle contol adjustment pot/screw on/near the ECM? If so, where's it located? I've been trying to fine tune and methodically work out some idle issues. I thought it would be good to know the status on that as I moved forward.
Obviously, I know where the ECM is - I've just never seen that adjustment feature in the near vacinity. Thanks. |

I don't think the 71 1.7L ECU had the idle mix screw. (IMG:style_emoticons/default/dry.gif)

QUOTE(Bleyseng @ May 23 2007, 07:52 PM)  (IMG:style_emoticons/default/agree.gif) My '73 2.0 has one. Car runs best with it turned all the way to the right. '73 may have been the first or only year, I'm not sure which. I do know the MPS and CHT are unique tot he '73 2.0. |

1.7 idle knob ECUs probably started sometime in 72.
if you pull the ECU you'll know if you got it or not. Grey knob on one of the long skinny sides that goes 22 clicks.... |
