Q: Car stalling since EGR valve replacement

asked by on

The car has been stalling ever since, I put a new EGR valve on.

You may have a bad EGR valve or it may be stuck open. Sometimes you can push on the rubber diaphragm on the EGR valve and it will free it up. I would recommend having a technician come out and inspect for vacuum leaks and check the new EGR valve to see if it is operating correctly.
