I just installed new AC plugs in my '90 2.5L Grand Am and now during
acceleration it hesitates and then backfires. I am 100% positive I did not
cross any wires and the plugs are properly gapped. I did not torque in the
plugs. Is this necessary, and if so, what should they be torqued in at?

Thanks.
