Engine Performance problem
1997 Toyota Landcruiser 6 cyl Four Wheel Drive Automatic 150, 00 miles
EGR code, excessive flow ( PO402)
Have removed and cleaned egr valve and code keeps recurring, watched egr work in scan tool and all looks good. Egr temp raises with flow however the code keeps recurring. Please advise. Seams to be getting terrible fuel mileage as well.
