While I am driving and even in cruise control the revs will drop and come back up again straight away. Some times it’s continuous.

Hi,
Has the check engine light ever come on when this happens? If so, you should have the computer scanned. Most parts stores will do it free of charge. If it hasn't, I would start by checking fuel pressure to make sure the pump is performing properly. Here is a link that shows how it is done:

Let me know if you have questions.
