I would also look for loose equipment, snagged cables, and software settings. It sounds like you image using TSX software so maybe try a simple stand alone program and see what happens without TSX. What camera/guider are you using?

P.S. unplugging the keypad won't do a thing one way or other. The keypad does not communicate with the mount unless you push one of the buttons. It is totally silent at all times and does not interfere in any way with any other program that you connect to the mount.
Guide at 1x. Going slower will not help.
Make sure you have a good calibration run.
Remove all backlash compensation, both in the keypad and in the guide software.
If using PHD2, you should first use the mount wizard to find out what you have fundamentally. You can find out things like PE, Dec backlash, sky scintillation and other good stuff.
A good calibration near the celestial equator and meridian is a MUST. Without that, you won't be able to guide successfully.
I have a usually reliable AP1600 mount.
