What kind of noise was it making from the back of your car?

If the egr failed I wouldn't worry (unless its stuck up!) or you worry about fuel economy and power gains.

It sounds like you have a few problems- almost sounds like your O2 sensor is going out too.


Is the intake really really loud? Does it sound like you have race cams now? Could you get the car over 30mph?

If you answerd Yes,Yes,and No. than your O2 sensor is out.

well my car is able to go over 45mph i dont get alot of noise form the intake or so... when i was stop at a light and my car wanted to die out it sounded like my fuel pump or so in the rear wanted to turn off also... but that was for a split second... im going to drive her around and see if the code comes back since i disconnect the battary and if it does i'll look into it more...feedback?

it should be the egr solenoid, there isnt much to it, someone said you can just clean it out, sometimes gunk builds up around the valve and stops it from working
