Torque converter won't cause a misfire mate.
Misfire will be one of two things - fuel or spark. On multipoint EFI vehicles, I always tend to look at the spark side of things first.
If you want the bush mechanic's way of diagnosing something like this, disconnect one plug lead and go for a drive. It'll run like shit. But see if you can reproduce the misfire. If you can, then reconnect the plug lead you disconnected, and disconnect a different one and repeat. When you can't get the misfire, that's your cylinder in all likelihood. Work backwards from there. Can you swap coil packs between cylinders? If so, do it and see if the misfire follows the coil pack. If it doesn't, try something else. Like a spark plug.
There's plenty you can do without actually replacing any components, to isolate exactly where the problem is coming from.
