I've been told that it may be the coil pack. Where is it located and is it difficult to replace?

Do you
have the same problem?

Scan for codes and check fuel pressure first before replacing any part.

Both of the codes relate to the same thing, check cam position sensor, stuck open EGR valve, or blocked EGR passages. Also check fuel pressure. Fuel pressure should be 26-45 psi key on engine running
