I'm trying to clean out the EGR passages and I can't locate a diagram for the passages inside the throttle body or inside the plenum....I blow air in the EGR but not coming out anywhere.... plugged maybe but where?...I have been all over the net looking for a diagram of where the EGR holes come up in the intake track but I can't find it.... anybody know where I can look or an exact spot they are supposed to be

Thanks

The EGR valve takes exhaust gas from the tube to the manifold and allows it to go through the EGR valve into the manifold to mix exhaust gas with incoming air. The passages are where the valve mount to the intake.
