The check engine light in my vehicle came on for the first time about a year ago. I had the Intake Manifold/EGR valve cleaned and it turned off but, within 3 weeks it came back on again. My mechanic cannot figure out what is wrong with it and now sometimes when I'm stopped and idling I can see exhaust billowing up the rear of my vehicle. Do I need to replace the EGR valve or something else?
have the same problem?
