2008 Mazda3i - Bad throttle response/power once warmed up?
 

Hey guys,

I bought a 2008 mazda 3i 5spd (2.0L) and had it for about a month now.. It seems like when the car is cold, it has great throttle response and great acceleration/power throughout all gears.. but once the car is warmed up to operating temperature, throttle response is nonexistant/sluggish and there doesn't seem to be as much power any more.. except first gear of course.. Mainly the torque is being affected here.

I took the vehicle to the mazda stealership and they diagnosed the car and even test drove it.. a $105 carwash later, they said they couldn't find anything wrong.

Is it just me or has anyone else had this problem? I've never owned a vehicle that did this.

Thanks in advance!
