Question: how much does it cost to replace an iac valve?
Answer: When the engine is cold, the IAC valve helps to get it started. If it breaks down on you or starts to malfunction, then you are going to have to get it replaced. The cost of that, on average, will be between $115 and $500. You will likely pay about $70 for labor and anywhere from $45 to just over $400 for parts.
