for the record, it's next to impossible to reach with the intake manifold in place, and i'm pretty sure it would be even worse to put it back in right. You're going to need a special socket that's 1 1/16 in size if i remember correctly, it's only $10. Don't bother trying anything else like a wrench, vise grips, goose necks, crescent wrenchs, hammers, DBs, etc cuz i'm 99.9% it's not going to work.
