so the check engine light and subsequently the atts light turned on in my 98 sh. i took it to goudy honda because i had a coupon for a free diagnosis. i was told that the code is p0401 insufficient flow. they say they gotta remove the intake manifold to clean it and maybe change the egr valve for a whopping 800 plus dollars. no way can i afford that right now. ive heard that maybe cleaning out the egr ports might do the trick. im not mechanically inclined to try and fix this problem myself. im thinking to take it to a mechanic and see what they say. any ideas?
