that's egrc solenoid valve, you can go and get it check at any

parts store or buy a obdII code reader and erase it if the problem

persist replace the egrc solenoid, and have the code erased again

it should fix the problem, althougth i had a problem like that and

it wasn't the egrc, was the egr valve since goes connected to the

egrc can give you that problem chek if you have a code for egr, if

it shows the code i will suggest to replace the egr it's
