Subject:      High idle on '89 -- fixed?
Content-Type: text/plain; charset="us-ascii"; format=flowed

Working on my "new" '89 (have to fix that signature...). It was idling around 1250 rpm, pretty steady. I pulled the idle-stab module and looked at it under the 'scope -- generally it looked very nice but three of the terminals had barely visible (under 40x) solder cracks on the top side of the board, bottom side looked ok. One of the diodes also had just the suspicion of a crack on top side, looked ok on bottom side. I reflowed all the terminals and all the large components (caps, diodes, one resistor, driver transistors). Result -- on closed throttle, idles down to 1250 or so, then a number of seconds later drops down to about 850. I don't know whether that's strictly normal for a 2.1 or not, but it's definitely much better.
