Dave,

I actually saw one of the posts about cleaning the idle valve. Thats what made me go back and clean it again to begin with. I should have mentioned, I used a can of Gunk Carb Medic this time not gasoline. By the time I was done the valve would spring back freely if I inserted a small screwdriver and pulled forward on the slide.

Is there a definitive way to test the valve without having a second one available.

You mentioned in an earlier post about an improperly adjusted throttle body switch. Do you still think this is a possibility given the symptoms? Do they typically lose their adjustment or does something else affect it. Where is it? How would I check it. I do have a multimeter to check resistance.

Thanks for your help.

Marc
