1999 3.4L random miss fire-turns to nothing but miss fire

Alright, I know a few people have had almost the same problem but I want start fresh with this and see if any one has some new ideas or tips and tricks. 1999 4runner, 3.4L limited 204K so recently I've had erratic start ups, it seems to take a few seconds to crank over, then when it does it feels like it starts harder then normal. No problem I thought maybe it was time for a starter. Well a week ago it would crank and crank then start up and stay around 200-300 rpm and sounds/feels like there's a miss fire. It would come back to normal rpm when I gave it some gas. So today I go to start it this morning here on beautiful cold Colorado morning and it cranks and cranks then starts with a miss fire. And will not come out of it even by feeding it gas, it was pretty close to stalling out from the sounds of it. (Side info) I have a valve tick on my driver side) I will try and get a link to a video I shot tonight. So any ideas or help would be great. Fyi I have check all my electric concnetions and ever thing is intact and apparently operational. Thanks-Jake
