So I bought an ecm with a jet chip from a fellow member after I installed it in my 87 b2 it started idling at 2000. (before it idled around 1000) after tinkering around with it a bit I just put the old computer back in and it still does it. Now it will idle normal sometimes for a little bit then jump up to 2000 or it will idle down low then idle back up over and over. What could be my issue? Any and all help is welcome thanks.
