A code for crank shaft came up on the computer at Auto Zone

Check engine light is on took it to auto zone they said it was my egr valve and i replaced it and check engine light still on........ is it any other sensor that, the egr could have trigger

The check engine light will not go out on its own until usually after 20 or so starts.You need to back to Auto zone and have them hook up the analyzer again and clear the codes (they will do this for free). If the problem was your EGR valve, the light will then go out.

While running suddenly the service engine light comes on, my gages start acting funny and the car either stalls or runs very rough, when the light goes out the car runs fine again

You will need to take your car to an Auto Store (i.e. Auto Zone, O'Reilly's...) that have a FREE use of their diagnostic equipment to see what engine Error Code was set. From that, you can (kind of) tell what component(s) has failed or is failing and causing the service engine light to come on. Could be one of a dozen things like bad oxygen sensor, mass air flow sensor, EGR valve and on and on. Find the code and that should head you in the right direction.
Good Luck

hi, most of the time when these lights come on, its because of some sort of sensor failure. if you are not experiencing any noises or tapping in the engine compartment, this is only a failed sensor. you will have to get it diagnosed by the computer to know what specific sensor it may be. i suspect maybe a O2 sensor or egr valve. this is minor but, you Will need to get this repaired if possible.

Check engine light will not go out

Mileage? O2 sensor? Scanner - 35.00 at Advance/Auto Zone - can be a big help accessing trouble codes.
