Hi all-first off, let me first say I have tried to use the search function, as well as read through the manual, before posting here. I've made some progress, but still haven't solved my issue.
I took my DMC out 2 weeks ago. Ended up driving on the highway for about 30 minutes, which I usually don't do. About midway thru that drive, the idle started pegging around 1700-1800RPM. It's been this way since. Upon startup, it will waffle around the ideal 750-ish range for about 5 seconds, then it floats slowly up to 1700-ish, and stays there.
I checked my electrical connections, and everything seems securely seated around the idle speed motor(there's a loose harness at the near side of the intake, but I see no female counterpart to it). I adjusted the idle speed screw all the way out, so the striker very securely depresses the switch when closed-no change. (part of my problem is that the manual doesn't clearly denote the parts of the idle speed motor with names, so my language here is lacking, sorry!). I read in one thread to check for 12V at a point, but it wasn't clear to me which test point I should see 12V.
Any further pointers would be hugely appreciated. Thanks!
