put 12 volt power n ground to the 85-86 posts,either way is fine.you should hear it click.in the meantime have a multimeter hooked to the 30-87 posts.you should have continuity n feel the relay click at the same time.if both happens then thats a good relay.

Question Answered: 

the manufacturer has no recommended specific maintenance interval on 1994 and later models for your engine but 100,000 miles since last change is near the end for all timing belts in my experience.you may just need the egr passages cleaned or valve lash adjusted.tuff to diagnose online however but good luck.
