Pick of the car (Vitz 2004) decreased after spark plugs chan

So on Saturday I went to the Toyota people in I-9 Islamabad, to get my usual oil, oil filter and air filter changed. I also told them to do some 'engine tuning'. I have a Vitz 2004, and I've driven it for almost 35k kms since I bought it 2 years ago. Anyway they also changed the spark plugs. The spark plugs cost me Rs. 1040. This is the first time these have been changed since this car came from Japan. Now since this visit my car's pick and race has decreased considerably. The engine is making more noise than usual when I push on the accelerator and is having trouble increasing speed. Anyone has any idea what could be wrong? Are the spark plugs to blame?

Without any doubts the problem have developed after change of spark plugs. - did they recommend a plug change or you choose it.

what else have they done, any adjustments thru the OBD system ( the car computer) like advance retard or fuel mixture settings?

If you have the old plugs.. take back to the Toyota tell them to change the plugs .. see if performance is back, Shove those NEW plugs to their asses.
