Try cleaning the insides of the pots with some aerosol pot cleaner first.

WD-40 leaves residue. The lubricating properties of it are not it's primary purpose. Water Displacement is what it was designed for.

Carry a can in your 4x4. Spray down ignition parts to keep water from providing a path to ground for the spark from the coils, or coil in older vehicles.

Problem with it is dust sticks to it. Then it starts to build up.

I have used it for a number of years now.
It is a good substitute for the real stuff.
Almost as effective, but it does have its drawbacks; Leaves an oily residue if you use too much of it, and I think that is the main mechanism by which it works, washing away the contamination, and that sometimes results in using a larger liguid quantity than you would otherwise use with a product that was designed and made for the purpose of cleaning and restoring electrical contact issues.

Go to ratshack and get some electronics cleaner, WD-40 lol a local use it on a yaesu 101 Boom it burnt up. Use the real stuff dont be cheap.

de-oxit it works well, best I have found. CRC electronic contact cleaner is also good.

Just a thought here, but have you checked your mic connection to make sure all wires are soldered up good and secure? The 2000 requires a mic to receive, and could possibly be causing an issue?
