Needs another service,every 5000kms could be the injectors need to be cleaned.Did the transmission get serviced if its an auto?

7500 kms is a long time, or distance for that matter.

Remove, clean and refit your plugs.

Remove and clean the throttle body, be sure to remove the sensors before using any degreaser as it can stuff them up (Throttle position sensor and Idle Air Control)

Take the lid off of your plenum, plug the inlets with rags, use degreaser and clean rags to clean the inside of your plenum (Not much of a gain unless it is really bad)

Check your air filter too, oh and remove the engine fuse, try to crank the engine for a few seconds and replace the fuse again to reset your ECU.

I know that there is allot more you can do, but that is a start.

They can happily go 10,000ks without a service, this is what is in the owners service book in 10,000k intervals.... Although a lot of people prefer to do them every 5000ks.

It could possibly be one of the injectors,if you take them out and send them away to get cleaned the car will have its take off power restored
