Comments about Wells Vehicle Electronics Idle Air Control Valve:

Required for proper idle. Idle had been running fast and would not idle down. Tested with an ohm meter as required by the book and iac was bad. Replaced with Wells product which I have used their products before and had proper operation and longevity with. A "lifetime " warranty shows the faith in the product and only takes 20 min. to install and remove. Marty S.

      I'm happy to help, Marty mechanic! I see that the idle speed control actuator for your 2001 Hyundai Elantra 2.0L L4 specifies the resistance between terminal 1 and 2 at 10.5 - 14 ohms and 2 and 3 at 10 - 12.5 ohms. It sounds like you may have a product that is defective. I suggest taking the part to your local Advance Auto Parts store with your receipt for an exchange.
