You may want to check your PITOT connection where the tubes are joined with unions inside the faired area of the port side wing root (u need to remove the lower fairing..... While you are at it, u may want to check a couple things; first I'd blow a little compressed air through the line towards the pitot/static tube (NEVER TOWARDS THE ASI OR ANY OTHER INSTRUMENTS IF THEY ARE CONNECTED!!!) just to make sure that nothing is restricting your tubing and also to ensure you don't have the pitot and static lines mixed up
