P1509 2000 civic lx high idle
I have a high idle on my 2000 civic lx. It idles at roughly 1500 rpms. I checked my IACV for continuity. I got a reading of 40ohms. I replaced the iacv but still have the same issue even after purging any air out of cooling system. I bought an ecu and replaced the old one but no change. I believe the problem might be a bad wire but I can't see any visible damage. How do I test for a bad connection. Im in need of some help. Thanks.
