My 95 Misty v6 had allot of problems. The one thing I found that solved most of them was the connector that has the TPS wiring running through it. I unpluged it and found half the pins corroded. After a cleaning and dielectric greasing, I put it back together and everything started to work normaly. Before that, I had replaced allot of the sensors and allot of bad wiring. No CEL light now. Thanks for all the info I got from this sight.
