i have had a problem lately with my na i will start it up ant the tack is fine but if i drive down the road or i run it hard. like the tac moves up fast, and sometimes the tack will fall to 0 and not move. the car will still run and drive fine but the tack wont work. if i shut the car off and turn it back on it works for about 5 min then falls again. sometimes it will fall sometimes it might not. WTF is going on. someone please help me. thanks

Sounds like the expertise of mazda soldering! Bad solder joints most likely, time to start searching for all the little bugs, does your clock flash in and out too, and any other little mazda inserts you've come along?

Remember the Tach comes off the trailing plug coil pack. Check your connection, it may be loose.
