I just got the car from this lady and she is the second owner, the car has been sitting for about a year, she had had a new starter and alternator put in, plus a tune up before she parked it. But now it runs funny when I start it, it's like it's not getting a steady flow of gas, reving up and down consently until it's warms up! and than evens out like there's nothing wrong with it ?

Chances are the idle air control valve or the throttle position sensor is bad. Has the check engine light come on? Also, have you checked for vacuum leaks?
