Hi , I'm new to this. My gt will start to drop rpm when I brake. It's worse when the car is driven for a while. Also when its cold, on startup it will die immediately for a few times starting it. I cleaned the egr but it didn't help. Don't know if I need to replace it?

 

I am in the same situation Partner... I have been checking the forum and checking on the car what could be.
