I have a 1997 Ford Taurus GL. I currently have a CEL but that's for the cat converter. I've noticed that driving on the highway recently, the rpms are at about 36-3700 at ~70mph. Also, just from driving it around town I've noticed that it's not shifting to make the rpms lower, a.k.a. overdrive, right?
There's no speedo jumping or anything like that, so I'm not positive it's VSS related, however, the tranny shifts fine, which leads me to think it's something electrical. I'm just not too familiar with Fords to know.
