My car has been having extremely poor acceleration. The engine coil pack has been changed, and a tune up performed. However, the car still has poor acceleration. What do you think could be the problem.

Is the Malfunction Indicator Light showing and have you checked for trouble codes?
Was anything done prior to this?
There are many possibilities and improper repair can affect it as well.
