Rough idle when cold
I have a 2005 Acura TL my car drives very good when it's warm but in the morning when I drive it soon as I put the key in crank the engine the car runs really rough soon as the idle starts dropping then you runs rough ER it's misfiring in all Pistons and the engine light sometimes starts flashing but now the engine light is on I got a check. Bye buddy he checked it with a computer thing told me that is giving code P 30 something that means that all the Pistons are misfiring but soon as the car is warm it drives really good I hope somebody can help me with this problem or anybody have the same problem

You either need to stop using voice transcribing, or learn the syntax to get punctuation....it is nearly impossible to read the big long sentences.
Do you have new plugs or new coils? I'm not up too much on the multi-misfire issues....but from what I kind of recall from reading on here, plugs, coils, EGR, or ECM are the typical culprits and I think you have covered a few of them already.

I even change that ECU computer
I cannot figure out what's wrong with this car now when I'm driving and when I stop at a light I can tell that is misfiring but when I'm driving it's fine
I changed the plugs and the spark plugs new throttle body I clean the manifold the EGR port new gaskets and still doing it I'm kind of thinking could be the valves gasket

The thermostat can effect the car running ruff when cold, until the car warms up. Also coolant tubes run up the the air intake hose, where the hose connects to the mass airflow sensor and could have something to do with your problem.

First of all, is the Engine Light still on even after the engine warms up and driving?
If it is Yes, could you check your Power Steering fluid reservoir and see if it's empty or full? Is the fluid leaking? Check that and let me know.
