Idle Problem. Please Help
My Jza80 TT wont start in the morning unlless I have my foot on the throttle. When it warms up then it will idle at 500pm. It seems like the Idle control valve does not take any commands from the Ecu. Please give me a few guidelines, suggestions on where to look for the problem. Thanks

Its just kind of odd how the IACV works fine once you are warm but during cold start it doesnt seem to work. Do you notice any wires loose? Did you have any electrical problems before? I would try changing the IACV first then if that doesnt solve the problem we can trouble shoot some more. |

we won't really know much until he does at least a diagnostic... it very well may be the isc but pulling codes is always a good first step
