i have a ford f150 with either a bad egr valve or a missing hose. How do you know if your egr valve is bad? and is it worth it to fix it myself?
thanks

Are you sure that the EGR vavle is faulty?
Which tests have you run to verify this?
Has it set a code? if so, let me know
More info will help me help you!

I'm having the same problem f150 V6 2001 with 60k. Replaced Egr vavle still check engine light still on. Had it reset at Autozone. They told me that the same code came up for Egr. What should i check next?

If It Is A Code P0401 Po402 Or P0400 Replace The Dpfe Sensor
