Question about 1998 Honda Civic
Multiple cylinders, 2,3,and 4, cannot find definition for po1399. could it be the EGR valve sticking open?
The best way to test the egr is unplug the vac hose and put a vac pump and gauge on it and see if the egr moves in and out.
then u can check it for binding or sticking.
sometimes a chunk of carbon gets loose and gets stuck in the valve itself and therefor will need to be removed and the carbon cleaned out.
