Accord 2.2i -92 Problems with cooling fan.

Hi!

I have two problems with my beloved Honda Accord 2.2i -92:

1. The motor cooling fan is still running after I turn off the car. It
has never done this during the two years I've had it. It started about
1 week ago and does this even if I travel very short distances (like <
1 km). The fan goes for about 2-3 minutes and then it turns off.

2. The motor idling-rpm is usually around 8-900 rpm but now it goes up
to 2500 rpm then back to 800, up again, then down, up, down, in about
1 second intervals. This behaviour dissapears when the car is warm.

Could these two problems be sypthoms of the same error? Any ideas what
could be wrong?

Any help greatly appreciated.

Thanks in advance,
