1993 Toyota Corolla 4 cyl Two Wheel Drive Manual 205000 miles
I did not pass the Ohio echeck due to high NOX. I was told it may be due to a dirty or clogged egr valve. I would try to clean it, but I can't find it. Where exactly is it located? Is there an engine diagram or a picture somewhere on line?
