96 2.5tl acceleration problems

car idles and runs fine in park(even when you hit the gas). no problems til you shift into drive and it pulsates as you ease into the throttle. once it gets out of first gear or atleast above 15-20 mph it drives perfect. injector problems maybe? i dont know how to check for codes or even what code is what so i obviously havent checked that area yet. right now im just lookin for some advice on here. thanks for any help.
