Does anybody know where I can find a diy,or a write up on how to install a fuel tank pressure sensor. Car is a 97 civic cx, with b16a2 with p2t ecu. Just recently passed deq with a obd2a p30, but car ran horribly until enough readiness monitors were set so I can pass. So I want to find what components are needed and how to install ftp so I can permenently kill code 91!!!!!!
