I started after mant tries for a good idle at the fuel sytem ,I only successfully had it running after performing the above ,you can examine your fuel filter easily enough to start with ,buy a new one first and match it with the one off the car ,then open it up with a reciplicating saw after soaking it in a bucket of water (gas inside) ,the paper element should be somewhat clean .If you have no excessive sediment I would find out how to see what your fuel pressure has at the inlet of the fd, you may have a weak fuel pump or pumps.I did have to replace both filters and pump ,my yr only had 1 pump.
