i have a 2002 wrx with the usdm 2 liter turbo engine. ive had a short ram intake in it for about 20000 miles and about 5000 miles ago i had the fuel line replaced because of a leak. over all theres 63000 miles on the car. the upstream o2 sensor went bad the same time the fuel lines were replaced. i know this is premature. do those changes have anything to do with this o2 sensor going bad?
