Been chasing this one for a while.

the dissy & coil have both been replaced along with leads and plugs, all not long ago.

the motor has a tremor at idle for a year and it is noticable enough to annoy me. i still get good fuel economy but i have noticed a fair drop in performance. 0-100 times around 11.5 secs with the following mods.

i had a timing light on the motor a week ago and it was firing about (guesstimate) 5-10 degrees before the marker. this wasnt in diagnostic mode (i got my hands on one and just wanted to use it) so i dont know what it was really telling me sides that. i noticed that the advance was jumping a little forward and back from every revolution.

is there anything i could be missing with this?

I have au injectors in my EB and it seems alot smoother that would be the way to go...

i suggest with the miss, check dizzy map sensor or sensors

or spend the 80 to 100 dollars get it diganosed properly
