Hi Guys -- I have a 1996 Grand Marquis V8 which recently sprung 2 issues.
1. Does anyone have a guide or diagram they could link up as to what o2 sensor goes where? I gather that there are 4 of them & that they are not interchangable. Would Bank 2 Sensor 2 be the 2nd sensor post-cat? Upstream/downstream? I have never ever touched an o2 sensor before & know very little about them. I have googled the subject & just trying to complete what I know against what I dont.
2. Over the course of the last week or so, my right rear wheel (at least that is where I believe the sound is coming from) has developed a squeal & a tap ( like a ch-ch-ch-ch sound) ... usually it squeals then does the tap thing for anywhere from a couple seconds to a few minutes until it goes away. Theres no rhyme or reason or pattern. It will happen at any speed & whether I am turning or just driving in a straight line. It does it when it wants to & comes & goes how it pleases. Its extremely variable. I havent noticed any problems while driving it though either as far as vibrations or sway. And the noises will remain even after applying the brakes. Only thing I have noticed is that its more persistant from about 45mph & under. But it happens at any speed. Any thoughts?
Thanks for any help!!
