Engin light came on found code P030.1 engin hesitates
P0301 Cylinder #1 misfire. First of all check Spark plug, plug wire, Compression in #1 cylinder and if all are fine then I would be looking at the fuel pump !

it is your EGR Valve.
EGR stands for Exhaust Gas Recirculation. It is part of the vehicle emmissions system, and is used to reduce combustion temperature and pressure to control Oxides of Nitrogen. There are generally three parts to the EGR system: the EGR valve
, an actuator solenoid, and a differential pressure sensor EGR (DPFE). These things work together to deliver the correct amount of recirculation based on engine temperature, load, etc. The P0401 code means that OBD detected an insufficient amount of EGR.
Causes
A code P0401 most likely means one or more of the following has happened:
Possible Solutions
In fixing this code, it is quite common for people to just replace the EGR valve only to have the OBD code return. The EGR valve is not always the culprit.
LOCATION:
drivers side of the engine bay, just under the intake manifold plenum where the throttle body bolts up! If you take the air snokel off you'll see it better! It has a remote mountted vaccum solenoid with a 2 wire connector
going to it that you should be able to see near the throttle body.
Follow the hose from the solenoid down to the valve and you'll find it!

The problem is most likely to be with your vacuum line they put cheap rubber hose for this purpose. You should find a diagram at the front of the vehicle trace the hoses by this diagram. You most likely will find a bad piece of hose.

If you mean code P0441 - This Relates to Incorrect Purge Flow for Evaporative Emission System
