How to fix or change a egr valve?

if you fallow the hose comming out of air filter assembley it should lead you to the pcv valve the hose goes to the pcv and should come right off then you take the pcv valve out of the valve cover by just pulling it out and replace it with a new one

you will have to take off the coil packs and move them out of the way. then go in from the top. its kinda tight but just move whatever else is in the way

did you clean the EGR passages? take the valve back off. one hole will have exhaust, the other should have strong vacuum.ususally the passage gets plugged with carbon, from the valve to where it goes into the intake manifold. you may take a wire and carb cleaner to clean the passage.
