Hi all!

I have adjusted many valves before, but I need extra help for this one. The valve seems to be adjusted properly, but if the car sits idle for more than a few minutes the next up opening is very harsh. By UP opening I mean even before the UA (UP Acceleration) because I can definitely feel the UA to full speed and it is nicely adjusted. It almost feels as if the valve is internally losing its "prime". Any ideas?

Thanks,

S
