Drives fine. Shifts from first to second then when you would expect it to shift to third it starts to backfire and miss. Back off the throttle a bit and it will shift to third and then it is fine.

This is a classic misfire problem. I would do a full tune up with plug wires. Use all OEM spark plugs and wires. Here is a guide to help you:

Please run down this guide and report back.
