I have a 1990 crx HF... Ive been having an Idle problem lately... usually when the car engien is warmed up. It'll act fine when cold.. but once I get it warmed up (driving for a while) itll start to bogg down as if trying to turn off... always happens when at a stop light... RPM goes down from 1000 to 500 then starts bogging down.. then after 10 sec of bogging it goes back to 1000 and does every other stop light... (other problems) RPM gos from 1000 to 500 when I turn on lights @ night.... speedometer lights dim when bogging, when pressing on gas sometimes I can feel a difference in power (like if its struggling to rev)..it could be the alternator but just wondering if you all have any other suggestions?

 

The car has new distribuitor, spark pluggs, wires,& fuel filter... ?????

 

IACV valve. Take it off and clean it. Re-install. See if that helps..

 

thanx just saw a thread concerning this.. will try tomorrow and update!
