Had check engine light come on. Mechanic said needed EGR valve replaced. I gave them $353.33 and they replaced valve. Check engine light came back on, so they tried cleaning out carbon which they said had clogged new valve. After a couple more tries, they replaced valve again. But after replacin…

Carbon can’t accumulate in an EGR valve in a short time, unless there is something horribly wrong with the engine, which you would know, because the car would be nearly impossible to drive. You need a new mechanic.

is your car subject to emissions testing? If not, don’t worry about it…

I’m having a hard time believing there is any carbon build-up at all. This is a 2000 Accord. Why would there be a carbon build-up?

I don’t have the codes with me. Will post them tomorrow. Thanks

I agree with mcparadise. When you replace the EGR, which may not have been necessary, you MUST clean out all the carbon from the passages. Carbon may have been clogging the passages, leading to the code to begin with, and the old EGR may have been good.
