Dear all
I have been owning my car 11 months now. Although I always liked it, the car seemed pretty sluggish: it did not like to rev up, and 0-60 was about 11 seconds. When the AC was switched on I almost felt sorry for the car because the engine seemed so busy moving it. Also I noted that the transmission shifted quite hard. Recently I was driving at 4000rpm when there was a loud noise from the exhaust, sounded like "pufff!!!". Since then, the car has been changed to the better: It revs up to 6000 eagerly and the transmission shifts much smoother. Also, oil consumtption has diminished. Has anyone made a similar experience? I wonder whether the precats were clogged? Would you recommend to check the whole exhaust system?
