Stumbling 850

1995- 850 NA.
Alright...car running terrible...stumbling. Brought it to my friend who has a code reader (I didn't know about the onboard one). Codes: PO137, PO400, P-1310, P-301. He cleared all codes...now I am left with the results.
This all seemed to increase after a 'tune up' about two months ago...new plugs (the multi-prongs ones from Groton), new cap,wires and rotor. It is getting increasingly worse...stumbling along.
What to do?

Anytime I hear about poor running, I first look at vacuum, then MAF.

Looks like, and I will know for sure after ride tomorrow...Cracked insulator on #1 sparkplug...nice crack! It idled smoothly...long ride tomorrow. As for the EGR...looks like that will have to wait for some warmer weather.
