ok i have a 91 crx hf with an obdo b16 i replaced the map sensor cause i had a code 3 but the idle still goes up and down. the code went away though but the idle is still bad. any ideas what else it could be a friend told me it might be the idle control valve anyone agree. by the way i got a map sensor from a single cam eg will that make a difference? Thanks for your help in advance

 

could be, take the IACV off and clean it with carb cleaner. dont loose the " figure 8" o-ring.

check your timign also.

 

thanks man i'll do that tomorrow and see what happens
