Re: Missing at mid speeds, tachometer and temperature...
If motor stalls , did it? if not stalled, you are losing DC power 12v to the PCM, or other EFI parts. Im assuming you ment quit reg, at the misfire. and that the motor did not stall.

I used to have a 1999 Mitsubishi Eclipse with the same symptoms; my mechanic replaced the speed sensor ($65) and the problem went away. Take the car to auto zone and ask them to plug the computer, they normally do it free of charge. If it is the sensor, you may have to buy at the dealer.
It's tach, not tack, short for tachometer. Were these gauges installed by unionized people? It could have been the gauges' day off, as per their collective agreement. Most instrument panel woes are caused by bad grounds. Most panels are below the front glass, and if this leaks, guess where the water goes? Dashboard problems are a bear to fix sometimes, and costly in terms of labor. Have someone steal the car.
The Tachometer is used to report how many Rotations Per Minute (RPM) the engine is running at. The number will vary depending on your speed.
There is also a temperature gauge available on most models for engine temperature. It too can vary depending on engine speed, duration, elevation, etc. As long as it's below 212 degrees, you will be fine
2005 BUICK LESABRE TACHOMETER DOES NOT REGISTER WHEN ENGINE IS RUNNING. SOMETIMES IT BARELY MOVES, THEN GOES BACK TO 0
SAME CAR HAD SPEEDOMETER QUIT, REPLACED WITH NEW SENSOR, DROVE ABOUT 1300 MILES AND IT QUIT AGAIN. CLEANED THE SENSOR, WORKS OK NOW.
have you tried working on one problem at a time? have you check the body computer for any codes? and to also verify the bus line is ok. if you find nothing wrong with BCM or bus, try checking the speed sensor for an output signal or if the gear is bad.
spark plugs? spark plug wires? coil? if it shuts off when hot, and starts when cold, coil could be problem....could be radiator stopped up causing it too heat, and will go off wait a few and it'll start back up...
