I just had my EGR valve and hose and DPFE sensor replaced and the truck is running better than it has in quite a while except that whenever I turn to the left and pull into a parking space it dies.

I've read that it could be a bad power steering pump. This would make sense because mine is pretty noisy when I make a left or right turn. However, it has never caused the engine to stall before. This didn't begin happening until immediately after the recent maintenance.

Is there something I should be looking for that my be related to the new EGR valve/hose or DPFE sensor?

 

Check the power steering pressure sensor.

 

I'll do that. Thank you.

 

Follow your pressure hose from the pump to the steer gear and you will find it. You should have trouble code 52 if you have a bad pressure switch. It tells the PCU to up the idle when you turn/put a load on the motor. without the switch you die a lot.
