what is the approximate cost to replace air intake pumps on this vehicle?

This is a very common problem with Toyota and Lexus vehicles with the 4.7L engine. As well as the air pump that will need to be replaced there are three valves that are highly recommend to replace as well. All these parts sit under the intake manifold, so it can be a labor intrusive repair. Approximate cost to replace the parts and labor is $1500-$2000.
