when should the egr valve be cleaned and what is the best way to clean the egr valve? is it necessary to take it off and let it soak?

Most people just do a seafoam treatment. Look for it on youtube.

It's not necessarily the EGR. It could be the EGR temp sensor or the VSV is bad. It would also help to inspect the lines for a vac leak.
