P1504 Ford - TAURUS 200

Question

IF I REPLC THE IDLE AIR CONTROL VALVE WILL THAT CARE FOR THE PROBLEM OR WHAT ELSE MAY BE INVOLVED?

Answer 1

P1504 Idle air control valve

Is there any other code with this such as a EGR code. where the EGR flow is excessive or any vacuum leak such as the PCV hose or ruptured vacuum hose line. What else may be involved would be a vacuum leak, But if this code is by itself then you can just do the IAC valve.
