Honda Accord 1.8 2000 W Auto.
My Honda has seem to developed a very poor engine idle. It seems to be down to a very low 200rpm when warm. No error lights on the dashboard. Normally its around 600 rpm. Car seems to drive ok otherwise. Any ideas on what to look at first?

When my brothers accord suffered a similar-sounding ailment it was cured by cleaning the inside of the throttle body (which was very dirty and sticky).

If its just an idle problem then confine your initial investigations to the throttle body (as mentioned by Cyd). Clean it out and check the by-pass passages and hoses are all clean.
