f115TLRB YDS wont do ICV test

I have tried in vain ti get this test to work. Every time it goes to an error screen with no explaination for the error. Any one have an idea why?

That test does not work on earlier models, not if will work on a 2003 model or not. Does engine run ok?

no

doesn't idle well and stalls when returning to idle.

The diagnostic program didn't show anything out of range on the engine monitor or diagnostic menu?

No everything was in range. However I did discover that the ICV intermittently fails to actuate. I removed the valve started the engine and it ran smoothly at a high idle. I stuck my finger in the prot and was able to regulate the RPM lower and it ran perfectly smooth. I ordered the assembly and hope to get it soon.
