Running Rough

Running Rough
Hey I have just recently finished up my 4runner and I have been noticing a weird problem. So the story is, the 4runner runs great most of the time but sometimes it will run rough and misfire. This is the pattern I have noticed is when i first drive it in the mornings it runs awesome, but say i drive it for about 10 minutes go to a store and come out a bit later it starts to run not so great. It will continue to run bad until it sits for several hours. I have tried restarting it, resetting the ecu. still runs bad but like i said if it sits for several hours it is fine again, until i stop and come back out.
About a week ago i was driving it on a 4 hour trip and it was running not so good and about half way through the trip i felt like a surge and it was running great. So i am not sure what is going on here i am stumped.
I have read on a couple forums of people having similar issues and it turning out to be an injector but i cant figure out which one if any is struggling.
I have wired in my OBD2 and am not throwing any misfire codes.
Any ideas on where i should start on trying to figure this out?
Thanks everyone

Hmm I will take a look at them. I replaced the wires and plugs not even a month ago, but i did get them off of eBay so who knows. The plugs are denso and the wires are NGK. Has anyone had issues with this setup? I might just go get facotry wires and plugs and see if that helps. Thanks for everyones quick responses
