97 MKIV problem

excesss · 02-26-2007, 02:29 AM

Hi,
I recently purchased a 1997 N/A automatic supra. I put about 100 miles on it and the check engine light came on so I got a buddy to hook up his module to see what the code was. I dont remember the exact wording but it was something to do with insufficient exhaust flow (code PO401). He said it could be many things, possibly an EGR valve. Anyone have a problem like this or know what the problem is?
