Thank you for your answer. How can I reset the ECM.Could be a sticky IACV. Clean it out with carb cleaner and if that doesn't help, reset the ECM to see if resetting the adaptive values fix the problem. If all else fails, replace the IACV.
thank you,Unplug the battery for 10min and hold the brake for a few minutes to drain residual power in the system. From a cold start let the engine idle for 15min then drive carefully using less than 30% throttle on the highway for 10-20miles. This will relearn adaptive values for everything including your IACV.
Did you buy a genuine Hyundai IACV or a cheap knock off part?
It would be best if the engine is cold for the first startup after resetting the ECM. That way it gives the car a full cold to warm idle cycle to learn from.I will ask something, does the engine have to be cold?
I tried it when it was hot.Please use English with your responses. It's in the forum rules... and it makes it easier for us to answer without translating each response.

There is the same problem again
Can you take a close up picture of the IACV? I want to see the part number and brand name. I know that Bosch makes a couple variants that may not be compatible with the Tiburon because they are hardwired backwards for the Porsche/Audi vehicles. I have an IACV at home from a Porsche that will bolt up and plug into my car, but it won't idle because the open and close wires are opposite.

We bought the product in this picture from a different car and it was the same problem.
yes I looked at the colors it was different that way the problem was solved damnThanks for the follow up. That is actually a very common problem. because the connectors are identical except for their color.
