This weekend I removed my air pump. While in the process of the removal i checked my 5th and 6th ports neither of them worked of course. The were frozen shut. So i finishe air pump removal, block off plate, etc... The took of my 5th and 6th port actuators and unfroze them. (it took alot of WD40 and a few taps with a rubber mallet) but now they work really smooth. Then the test drive I felt a real difference in power better acceleration, better idle, and a real seat of the pants difference. Glad i did it. Thanks for all the write ups and walk thrus they really helped. Just wanted to post a succes story cause i am tired of all the bad stuff

 

YOu should )when you have some spare time and a gasket) take off the LIM and clean them up real good. I put mine in nearly as shiny as new ones I guess for now that will do for you.

 

Sorry, LIM?
