Hey, my car jerks a good 3 to 4 times when deceling on first gear arround 1000 rpms before becoming smooth! At idle when stopping if engine is warm, the idle has trouble getting down to 700 and the engine make a little sqick-grinding sound...after 3-4 struggles it comes down to 700 rpm (if I give it a bit of gas she comes down right away) ????
I have changed spark plugs and wires, distributer cap and roter, I have done a fuel purge and cleaned out me throttle body!!!

Where should I look next???

when yer slowing down... try putting your foot under the gas pedal and pull it up.. i know my car jerks around when i slow down, but when i pull the gas pedal out like 1mm its fine...

 

will try but I don't know if that would explain the sounds that the engines makes when trying to idle???
