emission failure high nox- egr solenoid not passing vacuum. 240 1990

Hi,
Car is 1990 240 non turbo. 133000 mi.
My car pased co, and hc with flying colors, but nox was up in the stratosphere(2100). Will a failed egr vacuum solenoid account for such a high rise. Or should I expect something else.The egr valve is functional, there is vacuum, but its not passing through the solenoid.
I wired my hot air door closed awhile ago so that shouldnt be a problem.
My timing is dead on at about 12degree.
My engine temp guage says the engine temp stays withing the proper range.
I do, however, keep getting a lean air code.
What Im wondering is will replacing the solenoid get me pass smog?

Any advice accepted.

Thanks
Lawrence
