Hi i have got a 04 vrs , i have covered about 84k

lately the car does not seem very responsive when i put my foot down

any ideas

Disconnect the battery for 10 minutes. Like most modern cars it has learned your driving style and adapted the ECU to suit. if you haven't been thrashing it constantly it starts to think eco.

Warmer the weather, the slower the car feels. Cooler air is more dense meaning more fuel to burn so feels a little more responsive.

when was the las time you changed the fuel filter. if you aint had one for a while may be worth changing it.
