Trouble Code 1-5-4 (EGR System) 850 1994

Hello- Does this code indicate a vacuum leak? I think it's EGR system flow too high. I cleared it almost a year ago to the day, and it comes back again! Maybe it's something to do with cold weather?!? Car runs fine, 30mph, no other codes. I cleared it about an hour ago, now I'll wait to see if it's gone for another year...
