Did you replace anything on your car recently? It Sounds like a boost leak to me. First make sure your intercooler is on tight, Then Id check all of your gaskets on your downpipe, bov and on your cold air intake. If you cant find the problem then do a compression test and maybe check your vacuum lines aswell. If all else fails hook up a tactrix cable to a laptop and see if anything is acting up.
