I have noticed a problem with my Alfa. It only seems to happen when the engine gets hot, around 175 which is its normal running temperature. It sounds like the car is not getting either enough gas or air when I accelerate. There is also some slight jerking when going from a stand still into first and an even less but constant jerking when I am cruising at a constant speed. When this happens, the engine has a rather throaty sound during the acceleration in the 1st and 2nd gear until it gets past 2500 rpms. I have made sure that the air intake hose is tight, but have noticed some slight cracking. I am thinking about replacing that, but I am not sure where to go to get the part. My concern is that something else besides the air intake hose is causing the problem. Again, this only seems to happen with the engine is hot and when I accelerate. Any help I can get would be greatly appreciated.
