CHEVROLET BLAZER EGR VALVE PROBLEM

1999 Chevrolet Blazer

Check engine light came on, had it tested they said it was the egr valve or censer, could it be a vacume leak, it's losing power when driving and not wanting to shift

Need a better description of the diagnostic fault code. There' more than one related to the EGR valve, but fault codes never say to replace parts. They only indicate the circuit or system that needs further diagnosis. A vacuum leak should not cause an EGR code unless possibly if the leak is in the hose going TO that valve.
