1995 Mercury Mystique missing intermitantly

if your not getting enough voltage output from the coil then you either have bad wires or a bad coil. the coil is either going to get a ground command for spark at the coil or not. if its getting the ground control to spark the coil and output is not what it should be i would suggest replacing coil, plugs and wires.

thanks for the direction on that...not much room to get to plugs 1,2 and 3...and why just that bank when the corresponding cylinders of the three coils(4,5 and 6) fire fine?

thats a good question and i wish i had a definite answer for you but i dont. i dont know whats going on inside the coil, i can assume maybe that side shares a ground inside the coil housing(this is purely a guess). are you using a spark tester that tests coil output voltage?

nah...I'm old school...grab the wires wet handed and measure how high I jump...lol...I don't have a volatage output tester...just looking @ the brightness of the inline spark tester...I ordered an OBD 1 code reader(numerical readout) 10 days ago but it hasn't shown up yet...figured that it would at least verify which cylinders aren't hitting...managed to squeeze a stheoscope probe between the wiring harness covers and intake manifold...all of the injectors are clicking evenly from idle thru about 2700 R's...thanks again for your thoughts on this...
