2004 Ford F150 XLT Super Cab 4.6L with check engine code P0506, how do I fix this problem?
Hi there
This code means the idle speed is lower then expected. This could be due to the IAC or a dirty throttle body. You will also want to check for vacuum leaks. Here is some more info on the code. There is also a factory service bulletin for this.
