problem is rough idle engine hesitation at idle or when stop at traffic light.

4 oxygen sensor.
EGR valve.
purge control valve.

yesterday i change the 2 front o2 sensors but no difference and the codes still shwoing.

i tried change fuel pump
clean fuel injectors.

EGR valve.
you need to change it,

thank u for the reply.

About two weeks ago i went to garage and they have a used egr valve the replace it and their is differnece in the car performnace.

I test the car with for two weeks its much better then before only some times car stalls like in 4 days one time stalls.

Yesterday went the same garage and we fix the new egr valve.
the car again stalls rough idle.

We think the previous egr valve which the garage peoples fixed from their side is little dump so that why some time stalls and we fixed the new egr valve but with the new valve the problem came back.

Still showing the all the codes 4 o2sensors
Egr valve
Purge control valve.
But we fixed the new egr valve but the egr gasket which i bought new when fitting used egr valve is the same.
