First lets start by checking what codes you have. off the top of my head.. Fuel pressure regulator? TPS, MAF, ECT, and then O2. The O2 sensor is the last on this list post back with codes. oh snap you said Ijz. bummer I've never owned one. Perhaps someone else can chime in. __________________ 92 Ma71 7mGTE Auto.
