If thats happening then a fault code must be set, bring your vehicle to autozone for a free computer scan, bring the codes back to me for diagnosis.

Ok, that is cylinder four misfire, start by checking spark plugs, specifically number four cylinder, but if your gonna change it you might as well change them all, check the wires, that cylinder wire could be arcing against the block too. You want to feel the wire, do like a little bending of the wire to see if there is actually a bad corrosion inside the center of the wire. Get back to me with your findings.
