I had a check engine light come on with p0401 code and by what people said it was the EGR Valve I replaced it and it still was on and that was about 5 months ago it went off the other day for about a week and came back on? anybody know what the problem could be?
Yeah I disconnected the battery to reset it right after and it cam back on about a week later...? I was reading and it could be a EGR differential pressure feedback sensor but I have no Idea where to buy them and hopefully that could fix it. Is there a site online that I could buy this part for my car?
Carbon Build up, i was reading about that how much prob do you think it would cost to get it cleaned out and is it bad to be driving like this?
