Egr engine warning light
Hello every one, i looking for solution, i got the problem, egr valve error P0404
I plug computer, and it show me EGR valve problem, i replace to new one, plug connector
To valve my engine revolutions start going up and down, i did test drive, no performance was lost but on 1000 rpm when shift gear, lightly touch gas pedal(axelerator) it losing and picking up power, making car shudering, on low rpm. When i disconnect power plug from egr, car works perfect but on panel pops out : engine control system filure, P0404 EGR valve
I got EGR blocling plate, block the egr valve, to stop emissions coming true system
And keap egr pluged in, still p0404 pops out. Any sugestions???
