Hi all. So read on another forum last night about being able to simply unplug the connector for egr valve on 06+ powerstrokes while the motor is shut off and the valve will stay closed basically acting as a block. It also said it would only throw a soft code. Did it last night just to try it, drove around, everything felt good and no CEL. However, after start up this morning, CEL comes on. Just wanted to make sure this is legit until I can afford to buy an actual delete. Thanks for your help.
