idling problem

[rayman]

my dad has a manual 92 accord ex. when i start the car and warm it up, the idling is fine but after driving it for a while the rpm's will drop down to 500 and stay their unless i accelerate. any ideas of what the solution might be would be helpful.

if it is not surging then all you should have to do is adjust the idle a little bit.

aint got nothing to worry about when its at 500...but if u want to adjust it then adjust the throttle cable on ur IM.

Hmm oem is around 700 if I remember. Might just need to bump it up a bit or your tach could be reading off since most factories do. Is it sitting good at idle though no wanting to die or anything? If its fine I wouldnt touch it.

thanks for the help guys but to answer ur question nail05, the car feels like its on the verge of turning off(but doesnt). o i forgot to mention that my check engine light comes on after this happens but goes away when i turn it off and then on again. any idea of what the problem might be? would adjusing my idle stop the check engine light from appearing or do i have bigger problems?

There is a two pin connector on your passenger side under the dash takes some digging but easy to find. Its blue. Anyway get a paper clip or something and jump it. Turn the key to the on position and see how many times it flashes. That will give you a code and post it on here. There are long and short flashes. Short = 1 Long = 10

check for cel's and any cut vacum lines.
