installed new egr valve and check engine light still won’t stay off
Was there a question in there?
What code or codes are set here? (Most auto parts stores will read them for free.)
What year is this car? How many miles does it have? Is all maintenance up to date? How does the engine feel and sound? Why did you replace the EGR valve?
Exact fault code
Once you post that, I will post something that may help
Did the CEL come on after the EGR was replaced? Or was it on before too, and that’s why you replaced it?
