my 92 ls 400 has about 230000 miles on it and it develop a dead miss across the entire tach range under load or not very suddenly one day last week. I, doing the obvious first replace the plugs, wires,both caps,and rotor buttons, and it still has the same miss. I put a stethiscope on the injectors and sounds as if they are all working and I am at loss as to where to go from here. I live in a fairly rural area and no one works on these enough to have common knowledge of common problems. I was hoping you would have a suggestion as to where to look now.
Thanks
