98 Accord - Catalylic Converter?

I was told by the dealer that I will need a catalytic converter soon. Car is not idling correctly, feels like it is going to stall then picks up again
at idle.
Anyone else had this issue? Converter is quite expensive at the Honda stealership...

Those are not symptoms of catalytic converter problems. Cat symptoms fall into two categories: those that announce themselves by the "check engine" light coming on and those caused by the catalyst becoming plugged. You don't have the first, with codes that point to the cat, right? And plugged cats are more of a problem when you push on the accelerator than they are at idle. Sometimes they have chunks of sintered debris floating around that cause intermittent stumbling, but again that is more of an "on the road" problem than an idle problem.
If the tune-up parts (spark wires, rotor, cap) haven't been changed since new, now is the time to do that. Use only OEM - new aftermarket forms of those parts have been known to cause grief. Change the spark plugs, too, but you can use NGKs for those if you want. Cover another base by adding a bottle of Techron to the tank, unless you have been using "top tier" gasoline semi-regularly. If the problems still persist we're looking at intake problems... or possibly ignition.

Yep...the engine light does come on sporadicly then goes off. Hence, the dealer telling me the issue with the engine light is catalytic in nature.
Great advice on the tune-up (plugs, rotor and wires). Did the Techron thing a few months ago.
Any easy fix for the converter?

What is the error code? Is it P0420?
