87 honda accord-idling high
 

With no warning lights, my 1987 Honda Accord began to idle high while
driving on the highway. I could see I was only giving it a slight amount of
gas. Once in town, it was running 3 & 4 rpms while in neutral. After about
20 minutes of stop and go (I was putting it in 1st gear at stops with my
feet pressing the clutch and break enough to keep the engine low) it was
running warm and gave what was likely a burning odor.

The car has 177K miles on it and is a very reliable car.

Does anyone have suggestions to what may cause this, how I can fix it, and/
or how much this may cost. I don't have any money for large repairs right
now.

Any information is greatly appreciated! Happy 2004
