Hello all. I drove my 92 a couple days ago when it was about 20 degrees outside. It started fine but it did not want to keep running. I had to press down the gas pedal slightly to keep it running. After the engine warmed up it would idle like normal. When I finally got to work I put it in park (yeah, it's a slushbox) and the idle jumped up to around 1100 or 1200 rpm and stayed there. Why would it have a low idle when cold but a high idle when warm? It's like the temp sensor is backwards.
