I have a similar problem with my '95 V-6. The speedometer is electronic (built in late model year for 95). I had just replaced my bank 1 (back one) O2 sensor. After installing the new sensor, I disconnected the Neg. battery post and let it sit for 10 mins. Then reconnected it and went for a test drive. The speedo and odometer had stopped working (worked fine before). The engine also stalls and runs poorly at times. Other times it runs great, more power then before. I also have 130,000+ miles (136,000). I am wondering if there is a fuse or something somewhere that went out.
Do you have any engine problems? I have a manual trans. so I am not having any tranny problems?
Anyone have any ideas?
Thanks!!
