Nothing is next. Your revs are limited to 3000 when in park. Nothing is wrong.

No prob. Your truck runs fine when it's in gear, right?

The RPM and speed limiter both work by cutting off fuel injection. This is why it seems like it is surging... cause it is. Its having the fuel cut off and then turned back on. The same thing will happen if you hit the 90 something mph speed limiter.
