Q: Acceleration problem on a BMW 530i

asked by on

I'm wanting to buy this car but the owner says there is an acceleration problem

My car has 175000 miles.
My car has an automatic transmission.

There are a number of things that may cause the car to hesitate when accelerating such as low fuel pressure, a dirty or faulty mass air flow sensor, clogged or dirty fuel injectors, a faulty throttle position sensor or potentially a bad fuel pump. Other things like a vacuum leak or faulty ignition components such as bad spark plugs or spark plug wires may also cause this kind of hesitation when accelerating.

I would suggest checking the Kelly Blue Book website with specifics related to your zip code as market prices of cars vary by zip code. This will give you a baseline for determining whether or not the car is within a general range of the asking price. Secondly, as you know, with any car the life expectancy of it depends largely on the maintenance schedule the owner has maintained, the driving conditions it is subjected to, the driving habits of the owner and many other factors. Often times when a car has had internal damage or even slight cosmetic damage, it may be difficult to tell without looking closely or performing an in depth inspection. As with any vehicle, proper maintenance schedules are a key factor to prolonging the longevity of the vehicle and avoiding unnecessary costly repair bills due to neglecting proper maintenance intervals. I would suggest having an expert from Your Mechanic come to your location to perform a thorough pre-purchase inspection prior to making your purchase.
