What plugs did you use? I had a guy put some in an S10 for me once and he broke the plug in half! It was just sitting on the motor ready to fall off. Double check your connections and see if the gap is right on the plugs.

Does it rev up fine or a sputtering noise happen..... I've noticed with my 95 bird 4.6 that I had a slight vaccine leak and I thought I was killing plugs or wires but it was a slight leak and it ran rough... or do the wire check to see which one it is by pulling from the pack individually while its running if there is a change in the idle its not the one if no change then either wire plug or the pack is bad

If you leaked all of it's vaccine out, it'll get sick...

just not smooth a little skip,,,no hesitation ,it screws,,,except for the shudder ,from a stand still,everyone says mercon 5 will take care of the shudder

well im not too sure about a 93 mark 3, but if you have a 8, i would definatley double check all your wires are on tight and did you use any dielectric grease on the s?
