dkim400 Posted January 25, 2011 Share Posted January 25, 2011 Couple days ago I did my own check engine light on my 91 ls. Brought up code 71. I figured it was the egr valve, or the whole assem. bt when i went into my local lexus parts place they said its most likely going to be the egr pipe. he said its a pain to replace, having to lift the whole motor and removing various things. does anyone know a quick and easy way around this?
