If your car runs bad with an EGR code then I would suggest that the EGR valve be replaced. I would like to know what code was set on your computer. It would help greatly. When the EGR malfunctions, you will have rough idle and possible stalling. If you have a code indicating EGR it may also condem the cat converter.Please show any codes that are set. Thanks Moe

Have an auto parts store check for the code. It is possible that you have a bad O2 sensor or your catalytic converter is clogged.

2001 buick century failed emission twice. we had a new catalytic converter put in, new egr valve,egr passage cleaned,new oil pressure sensor and new idle control valve. the check engine light goes off


Depends on where the failure occurs. Is the idle and low speed where it fails or the high rpm? Troubleshooting will be more exact if that is known

Buick 2001 century check has the code p1404. is it safe to drive the car until we can have it fixed?


Hello Momma.
This code has set because a fault was detected in the exhaust gas recirculation system (EGR).
If your car is running normally, no chugging or rough running, it isn't a serious issue. But you should have it looked at to determine why it set.
Often it's because the pin inside the EGR valve is sticking or carboned.
If this valve sticks it can allow exhaust gas into the intake when it should not be and cause your engine to stumble at idle or low speeds.
It will not damage anything over a short period of time.

Thank you for using FixYa.
Best of the season to you.
