Fishy928S4

Have not driven the 87 S4 atuo in about a month. Took her out last night and once she warmed up she idles at about 200rpm and stalled once. When I put it in park the idle jumped back up to about 600-700rpm. Put it back in "D" and the idle falls again and she nearly stalls.

Let sit overnight and same today. She only does this once the engine is warmed up which is about 10 min of driving or so.

Does this sound like Temp2 sensor has gone bad?

Edit : Just saw the other thread with a similar problem.
