Rough running on a 1995

I bought a 95 325is the car starts fine but when comes down to idle it dies and when rev it up it runs ruff to about 2000rpm. I know some cars have IAC's on the throttle body does this car? The battery was dead so i charged it and ran it for a while to see if it would relearn it but no luck and now the check engine light is on. What could this be? Is there a way to check the codes on the car without taking it in? What is the stock style spark plug? I was amaized that a dealer wanted $18 each?

You should be able to read the codes without a code reader on your 1995. Check out my article here: http://www.pelicanparts.com/bmw/techarticles/Mult-Code_Reading/Mult-Code_Reading.htm The codes should give you a big clue as to what the exact problem is.
