Had EGR and upstream O2 sensor replaced problem still existing. idle breaks when stopping then no power then it bounces back. Erratic and varying. Fault codes came back?

This could be a couple things if they are related but we need to start with what the actual code is.

Let's start with what the actual codes are and we can run through some testing to find out possible causes. Thanks
