My truck has an issue when I start it it will start but then kinda bog down then back up and down for about a minute or two then you can hear it settle out and runs just fine. Only does it when engine is cold. I have replaced all sensors on throttle body new plugs and new exhaust system any suggestions please

 

Have you cleaned the throttle body? IAC well tends to build up crap in it.

 

I am starting to have the same issue. When the engine is sitting cold for a while and i start it up it will idle up and down until it warms up and then it will run fine. Also when i put it in neutral and roll to a stop the rpms will slowly go up and down but seems to stay normal at a stop
