Miss under low load only when warms up?

Cold start driving around runs fine, when warms up has slight miss under low load when it misses I can floor it and it goes away? Just changed o2 did not help, anybody?

I had something like that happen to mine years ago. You can squeeze the EGR diaphram with your GLOVED hand, while the engine is running, it should cause the engine to run different of die. I had to take the top off of the intake, and clean out the EGR port. Hope this helps.

You might need to check the coil. When a coil gets hot it will start to miss if its going bad.
