Asked by Sep 17, 2015 at 02:08 PM about the 1998 Buick Riviera Supercharged Coupe

Question type: Maintenance & Repair

Greetings, my 98 Riviera  for three months has pulled the above mentioned code. This code is reference to a defective gas cap and purge valve (both I have changed). This code P0442 also refers to a vent valve as  the possible culprit. I need help directing me to where this part is located. Then if that doesn't solve the problem my next step is to have a smoke test perform. Thanks..
