How much does this cost?

btech88 answered a question for me about my car sputtering. It is a 99 ford escort. He said " i would suggest having the egr, exhaust gas recirculation, system inspected for possible clogs or improper operation." How much would this typically cost?|||A new egr valve, installed would be about $75.00|||$0.01|||first you must take it to a garage have it looked at and get an estimate. Then you will know how "much it cost"
