Hello,

A clogged EGR valve can make the engine run rough.
A dirty EGR valve can also restrict performance and can lead to poor acceleration.

The EGR valve and the EGR tube can be cleaned out to restore performance.

Here is a video of how to test the EGR:

I have attached diagrams for your reference.

Please let me know of any questions.
Thank you.
