Default ETR Valve

To pass emissions, they are now telling me that I need the ETR Valve replaced. Does that sound accurate and what would you estimate the average cost to be? I know that labor charges will vary...

Thanks

Egr valves cost $50 to $100. The labor varies. What year is your car?

It's a 1994. That's about what the emissions dude told me regarding the price. I just hope that's the problem and not the CAT.

Do they test enissions on a dyno?

You can have the EGR system tested for proper operation and the ECM should throw a code if it isn't functioning properly. Have it checked before throwing $$ at it.
