P1506 Idle Air Control Overspeed Error

[stangin]

Anyone heard of a "P1506 Idle Air Control Overspeed Error" ? I have O/R X so I need the mil eliminator for that.. actually will turn off the back two in my new tune on the way, but have not seen a P1506 code before. I dyno'd my KB last week with lots of belt slippage, actually pretty much screaded the belt. Could this have something to do with it?

NM, found it on the search.. idle too high, darn TB

What TB are you using with the KB? What's your TPS voltage?

You have to get the idle down under 800 or so. Preferrably closer to 750. That should solve the problem.

Actually it idles around 750 or so, but is slow to go back to idle.. I suspect the TPS voltage might be high, I never checked it after the KB install, seemed to idle and run great from the first time I fired it up after the KB install, just lazy I guess. It is the Accufab.
