Hi there:

In most cases acceleration issues are caused by restriction of fuel or air into the fuel injection system to be burned inside the combustion chamber. This could be the result of damaged mass air flow sensors, EGR valve, O2 sensors or simply due to dirty throttle body or fuel injectors. Due to the fact that multiple components cause these symptoms, you should contact one of our mobile mechanics complete a car is slow to accelerate inspection; so they can pinpoint the source of your troubles.
