Well, as you may know there are many things that can cause this. Although I am no expert I would start by resetting the computer. Disconnect both battery terminals and touch them together for 30 seconds. Also I would check the fuel pressure and exhaust system. Might think about running a cleaner through the system too in case those injectors are cruddy. And just to reassure you there isn't many people on at this late our so you'll get more (and probably better ) help in the morning.
