Could be a bunch of things, but I would start with bad gas, severe vacuum/boost leak, timing off, TPS sensor bad. A little more info would help others help you. Did this just start or did it happen after any new parts? Has your car been sitting for a while?
 

Had the cyclone motor put in it and was having an idle problem think it was the fuel pressure regulator cuz it smelled like gas like if it was getting too much. Replaced the fpr and got it running a lil better. Vacuum lines seem to be fine, the only thing i dont have is that white canister my motor didnt come with one. But i dont think that is causing my problem.
 

Problem solved, hose off the throttlebody came loose. Finally I get to drive this thing, only took 4 months to work out all the kinks.
