Is there any way to test the IC Pump other than "seat of the pants" test or taking it off and inspecting the inside and bench test . Mine is less then a year old and car has seemed to lost some punch. Also if the IC Pump is not working would the SC clutch still lock up. (I have added a LED light that shows when the SC is engaged) .I am going to try a Throttle Rest today and see it that helps.
Thanks
