Yes, vacuum leak.
Or, O2 sensors, bad spark plugs, contaminated fuel, weak ignition/coil/pack

difficult to say (a jolt could be a flat spot in the acceleration, poor fuel delivery, timing belt one tooth out) and normal with many cars and down to throttle body or poor manufacture spec or a simple fuel filter change

I read your problem on another thread. I think you need to explain what you mean by "jolt".
I took it to mean you felt a strong power surge, and now you are not feeling it?

If the coils were put on incorrectly, your care won't even idle correctly let alone build power smoothly.
Or, is the idle shaky and accle shaky as well?
Check your plugs and make sure they put the correct ones in, and gapped correctly.

The symptoms you had before the repair are now gone?

with my jolt this is what it does under wot (whatever that word stands for)

vvvvv ... vvvvvvvvvvv

like a space it stops breathing for that second but i suspect its firing problem as this only happened as soon as i got the chip...
