I have a 2006 Volvo S60 with 19,000 miles on it recently on acceleration on the highway the car felt like it lost all power to accellerate before the turbo kicked in then the check engine light went on. I brought it in to the dealer and they replaced the fuel pressure sensor (that what they said the code was). The car has been fine the last 2 weeks and yesterday, I did a hard acceleration and the car started bucking like it was gasping for air (or fuel) to accelerate. Any idea what the problem is or is it normal, i just accelerated to hard?
