egr unplug & block off
I have unpluged my EGR. I unhooked bottom plug. This weekend I plan to block off EGR at the intake, is there anything else I have to do? What does top plug on EGR do or control?There is a line on right side of EGR with 1/2 in pipe type thing- what does this line do? would it be a good idea to block off water lines to EGR cooler seeing how its not being used? I have a 2007 isx in a volvo.
Is this a good question?
