ok today i removed my air pump didnt work anyways was locked up also removed the a/c compressor and the pwr steering pump not a herd job by the way also run the hoses that went to and from the air pump together guess it seemed to make sense anyways i wsnt having anything over 3800 rpm like the 5th and 6th ports werent opening so i taped the air hose that use to goto the air pump and fead a hose in to it and run it to the line that operates the ports now i have an *** load of pwr over 3800 rpm but stalls under 3800 any ideas ??? thanks alot

 

S5? If so you need the air pump to open those ports.
