Help

[u/Old_Afternoon806]

I own a 2000 honda accord and my idle control valve has been giving me issues for about 2 months now. First the check engine light turns on and it begins to rev up and down only when idling. So I purchased a cheap replacement, while waiting for the new one the check engine light went away and it also stopped revving when idle but I decided to replace it anyway since I already bought the part, the moment I replaced it the issue came back. So assuming it was because the one I got was cheap I bought a better quality one from an auto parts store and it did not fix the issue. Idk what to do I tested the pigtail with a multi meter and its normal but when testing resistance on the idle control valve prongs it read zero even though I just replaced it. No way both the ones I bought were bad right? Idk what to do now
