You need to have the main relay replaced. I did that with my 1992 accord. ask around if you don't believe me. good luck. ro
Our 1997 Honda accord has had the same problem two times. Get the coolant recharged at your mechanic. We have had no problems for several years afterward.
On throttle body. It lets in extra air at idle when engine cold and throttle blade is closed.
It is broken. AC's usually blow cold air.
Have the vehicle scanned for codes. The codes will help determine the why.

The Honda Accord of 1998, just as any car in a frosty/cold morning, shakes because the engine is trying to warm itself up. Any car has gaps like the tiny edges between the bonnet and bodywork that can let the cold/ frost/snow in. A car's engine doesn't shake in '10 mintues' (some cars less/ some cars more) because then it's warm enough to not need a jig from the internal heater.
Hose going from engine to heater core may have burst. Check all your coolant hoses for leaks.
