Check your vacuum hoses for leaks, then the overrun cutoff valve.

The first thing I would check is the timing. It sounds as if it could be a little retarded.

its only started doin it recently, had more toruble today, whenever i got stuck in stop start traffic the main fuel pump starts buzzing then it missfires and cuts out,its always been a bit ify wen the gaugue is low on fuel so im gna do the lift pump first, looks like iv got a busy weekend :sad:cheers for the replies

^^ Replace the fuel filter and clean the mesh filter in tank.

I would not go for the complcated things yet. Do the things you can get at and go through a process of elimination or you could be wasting loads of time with no reward.
