have you tried swapping out the map sensor?

 

I just got back today from seeing a honda mechanic (back yard job).He said my iacv was fine but he noticed my throttle cable was sticking so he cleaned up the cable and where it connects to the tb.He also sprayed in the tb.He cleared the engine codes and the car idled perfect.I'm so happy to have the car working like it should it doesn't hesitate at all.It was the best $20.00 i have spent in a long time.Thanks for all the help.

 

Hello I just want to know if "kvinnie" has fixed the problem and how, i have the same problem and i changed map sensor i got one from accord that they the same and still have a problem with Fluctuating idle when the car is hot,when is cold no problems.I'm thinking about HO2 sensor can it be a problem too?
Where is OBD2 connector located on EXi honda Civic 2000 that is the same as 1999, do they have one??What else U can suggest me to check
thanx

 

first clean your iacv, then if it still persists then change out the tps

for cel pull codes
