I have even changed mine spark plug. the Spark plug wire. I am still unable to get why check ign light everytime pops up. this weekend i gone change the vacume. I am still unable to get why mine car is eating so much of gas. its like the half of milage i am getting only just 250 Miles on full gas tank.

Read this and have it checked out:
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.

replace the EGR valve VSV it is located on the back of the head. They go bad all the time.

This forum has a great thread on how to replace the VSV valve. I did mine a few weeks ago. I had to attack it from under the car. Put your car up on jack stands and get ready to have some fun. Those darn engineers didn't think the placement of this part out very well.
