Need Help, High Idle Problem

Hey guys need some help in trying to figure out a High Idle problem I have on my 1995 E150 5.7L Econoline Van. It starts up just fine and actually idles okay initially. I’ll put it in gear and drive off, after it warms up just a bit I’ll come to a stop and the van will be idling high. I have to stand on the break to keep it stopped.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>
<o> </o>
After searching in this forum I took some measurements (I also have an Engine Light on) and found what I believe was a bad TPS. In all I replace the IAC and the TPS and the problem hasn’t gone away. I get a fault code of PO0122 which is the TPS even after replacing it? So my question is it possible I got a bad TPS or something else could be causing the issue? Any help is much appreciated.<o></o>
Thanks

I had the same problem and it turned out to be the wrong voltage at the TPS because the throttle body stop had been messed with.

Having high idle issues also

Hi everyone, I have an 86 Econoline 150 (EFI) Is there an adjustment to lower the idle or is there something else that can be adjusted to lower it ?
