Re: High idle on each start
I want you to try lifting the EGR diaphragm with your fingers on a cold engine and see if it has strong spring pressure and see if it feels like it closes well consistently.
I also want you to disconnect and plug the vacuum hose to the EGR valve and see if it has a more stable idle at lower RPMs when you drive it.

If it is modified from what came stock from the factory, let us know that too.
