Miss firing?? Not sure!!!

[SVXgarcia]

Year:1992 SVX
Mileage: 135000

When car goes from zero mph I feel the car lacking power, even when I accelerate fast.
What exactly do I mean by lacking power, i will try to explain:
At take off the car feels almost as if the throttle cable was getting stuck and suddenly releases, causing the car to accelerate quickly. I can depress the pedal and the car will not go anywhere. Then suddenly the car accelerates.
When this happens I hear something clicking on the engine at the same time that the car quickly accelerates. Almost as if something was unclogging and finally the car accelerates again.
Problem happens only when the car comes to a full stop and I have to start from 0 mph. Doesn't happen on the highway.

Thank you for any help.
