Mitsubishi Repair: GLX Triton missing under load, full tank, premium fuel

Question
I have a 2000 GLX triton V6 3L petrol and under load or under 3grand revs the car seems to miss a little until you get over 3grand and then seems to run fine above that ratio, could you possibly know what is the problem, was thinking maybe injectors are dirty or slightly clogged maybe, really not sure? Any help would be appreciated,
Cheers Jason

Answer
Jason,
On an 8-9 year old vehicle, you're probably due for a tune-up.  This can include new plugs, wires, fuel filter, air filter, and various other inspections.  Have the ignition timing checked and adjusted if necessary.  Dirty injectors can usually be addressed with a bottle of injector cleaner along with a full tank of premium fuel.  
Good luck!
