2006 Taurus (automatic) loses gas and speed gauges while driving... intermittent.
I've got a 2006 Taurus with 185K Miles on it. Seems to be running fine, but every so often (and it seems to be associated with rapid acceleration) I will lose my gas and speed gauges, and I will get both a battery indicator light and airbag light on the dashboard. Sometimes it will stay that way for only a minute or so, and then the gauges will come back and those lights will go away. during all of this, the engine remains running, and I am getting no Check engine lights or fault codes.
The car has a new Interstate battery, and also a brand new alternator (both in December). The battery tests fine as of this morning, and last week I had the mechanic who installed the Alternator come check it and it also is still fine. Here are my next troubleshooting steps:
1. Check and re-tighten wiring between the fuse box and the batter (some of the metal cable is exposed)
2. Replace fuses
I've also noticed for the past few months that the shifting is not smooth. The engine will often over rev and then abruptly shift down. I also have had no cruise control for about the past year. Could all these issues be resulting from a bad speed sensor?
