Have you done a boost leak test? How old are your spark plugs?

I suggest doing a search for how to do a boost leak test. If you use the above link, you should be in good shape. Im sure there are other methods you may use to build a kit.

For the spark plugs, you should pull them and examine. If they look crusty and old, replace them with some NGK BPR6ES plugs. The plugs are cheap, and you should probably check these first.


Edit:
Typically a search will net very good results for any problem with DSMs.
