I have a 2007 Cadillac BLS 2.8 Auto and have been experiencing problems when I try to accelerate. When I have to accelerate the car just cuts out (loses power) and then after a few seconds cuts in again and repeats the sequence all the time until i lift my foot from the accelerator to have it in at a minimum distance - then the car will move evenly. But I have a problem when i have to pull away at a robot or go uphill since as soon as i accelerate the car cuts out. At times the car will go well for a while but then it will start doing the same thing again. The mechanic did a reading and says that it reports a fuel pressure problem but they say they do not know where to start to look for the problem because it could be caused by a multitude of possible causes. Has anyone experienced a similar problem and can you perhaps give me some guidance to solve this problem, please?
