Remove, Clean %26amp; Adjust Throttle Body! Have Injectors Cleaned! Coil %26amp;Plug Wires are Good? Are Distributor Cap %26amp; Rotor Cracked or Burnt (Replace)? Check Timing %26amp; Timing Belt! Full Diagnostic Read Out! Condition of Throttle Position %26amp; o2 Sensors?
I am not so sure but could it be the quality of petrol you are using because it happened to my dad when he used Mobil petrol when he stopped using it all the jerking went away.





But I am NOT so sure... Sorry....

What about the tranny? vacuum lines? distributor (your cars version of it)?
check the distributor and the timing, or the gas filter
