Most cars you can disconnect the battery for about 3 minutes to clear the codes if this does not work you may want to call an auto parts (Auto Zone ) checks and can clear codes if you have this kind of Auto parts store around if not call a few around to see if they offer this service

I was told reason for failing inspection was the ERG valve code said it was not functioning properly. If ERG valve is not working properly would this make this light come on? If I replace the ERG valve can I reset it myself?

to reset your check engine light, 1. Put the car in park 2.turn in on 3. rev it up to about 6000 rpm (not under, but anywhere over will do just fine) 4.slowly let it idle its way down by taking you foot off the gas.(be sure to let it got real slowly) 5.step on the brake and shift it downwards(reverse,neutral,drive,one,two,and back up to park making sure the transmission shifts during each gear). 6.turn the car off, count to ten, then turn it back on. this should work. its a mechanics secret!

Can't say I ever heard of the previous post's comment.

Pull the codes from the computer, match the code to the troubleshooting procedure, follow the procedure to find the source. Repair the source, light will go out if that was the only problem. There are "monitors" or self tests the computer runs the car through a drive cycle, if a problem occurs, it may not run all of the self tests until that problem is taken care. Therefore, another problem may exist. It is emission related. OR hook up a scanner that is capable of clearing codes, and hope that none are still active.

The light will shut off after you repair the car. It will store a the code as a non active code. When you disconnect the battery it will erase the non active codes only.........

What is wrong with a 1984 Nissan 300ZX non-turbo that will only start on a jump and continues to run with the positive battery wire disconnected?

You have a bad battery. Keep that up often enough, and you are going to end up with a bad alternator. Alternator's don't like being operated without a load going to them. Running the engine with either of the battery cables disconnected is not good.

It shouldn't. When the engine is running, electricity is supplied by the alternator, not the battery. If the engine dies when the battery is disconnected, the battery and/or some related part (such as the voltage regulator) is bad.
