Hi, I have a, 2000 ford falcon AU series 2, intech 4.0.
Can anyone help with my high idle problem.
About a week ago, I started my car and its idle went straight to 1100 rpms, then settles at 900 rpms.
I have checked for leaks, changed
IAC unit and checked for foulup in throttle unit but no change.
I voltage tested both new and old
IAC and they seem to read ok.
Voltage reads, unplugged engine running, 13.6 volts and engine off 12.4 volts. ohms reads 356 but im not sure if its 356 -35.6 - 3.56 as my multi doesn't state this.
I also lowered the idle speed on throttle but it ran bad and then when i load test it in gear it wanted to stall. I also tested it with aircon on and it readjusted the idle up automatically, so at least that works. Im not sure what more I can do, I appreciate any help. Thanks
