Bunny hopping engine

I have a 1986 3.6 manual, and when i let my foot off the accelerator, the car has a tendency to lurch forward and back (bunny hopping) shaking the whole car. The only way it stops is if i ride it out (which is uncomfortable), brake, accelerate or dip the clutch. I've recently serviced it with new filters, rotor arm, dizzy cap and plugs. Its made no difference. It doesn't make a difference if i take my foot off slow or fast, it will still sometimes bunny hop.
Any ideas please.

Mark.

Hi to anybody who might be curious, re bunny hopping.

I had to replace my radiator and i found that the connections and earths on the signal amplifier were not in good condition. when i replaced my rad, i duly cleaned all electrical connections, and miraculously the shuddering bunny hopping has stopped! (So far in the last 70 miles anyway).

Hi Mark,

Nearly all early 3.6's suffer from the bunny hopping :( . They suffered from a very early age and maybe your problem is still there. If your interested have a read of this article and it explains all :D
