When I do a running test on my 1994 Ranger 4.0L it will always give me a 411 and 412 code. The engine RPM's will rise and fall with the test but the same codes always come back. The IAC is working. Also how do i adjust the base idle? I am using a Snap-On scanner/reader and it says to fix these codes before continuing. So any ideas?
