take cover off servo run engine and look at motor you will see the spool rotate and the cables should move freely arund the spool then shut off engine and remove clip holding cables on spool slide cable off spool ,grab inner wire and pull and let snap back if feels stiff or binding take apart and clean allso at same time check cable lenght per owner,s manual

F7 APV valves do not cycle at start-up. RPM's must hit just about 7000 before you will see servo motor move....

F5's do cycle once when first started. If you have a F5 and you hav'nt checked your APV cables do it asap-it makes a huge difference in performance.
