Hi i need some help my punto has been running ok since i did the head gasket and belt. But today its really under powered. If im parked up and press the accelerator 50% of the way down it revs nice and slow up to 6k rev but if i put my foot flat to the floor it chokes (the engine gets really loud) and drops to 4k and work go above. Im assuming some sort of throttle problem but any help or advice would be appreciated. Not sure if it matters but i just replace the knock sensor yesterday ?
Thanks ryan
