This happened (sort of) to my '89 100Q. The problem turns out to be the dashpot plunger inside the throttle body. Sometimes, the plunger corrodes a little and makes it too sticky for the spring to return quickly (or at all: this cuased my 2500 RPM idle). My mechanic discovered that you can't get a new dashpot, it comes with a new throttle body. Right. $400 for a $1 spring/plunger. He took it out so I could look at polishing it or finding something at a boneyard. I never did. 2 years later, the car runs fine without it. -- Andrew L.
