ok so the damn car misses while im driving...its only when im driving and when the cars idleing runs beautiful....help me

you have a load sesnitive miss most likely due to faulty ignition parts such as a bad cap, rotor wires or plugs.......perform a cylinder balance test via ecm self test function and narrow it down to a cylinder/s

yea i can hear the tick when it arks just dont know which cylinders arking...damn air pump codes wont let me run a cylinder balance test so my dad said spray water ont he wires and see which one arks..

mjr46

get a water bottle /spray bottle and in the dark as it'll be easier to see mist ignition wires and cap and look for the arcing.. where you see it = bad wire..electricity travels through a path of least resistance to ground and when insulation of wires degrades such occurs

sprayed the coil....i see arking...damn msd coil i just bought like 30 days ago...

mjr46

as long as you didn't soak it big time then that may be the issue..to much water on the coil and it may create a path to ground to arc...but it could be cracked too causing the prob

it was arking pretty bad....and i remember when my first coil went bad the car drove the same way...but i ruled out coil cause i figured its a month old i bought it new theres no way, but my luck so im going to try and return it ( says 90 day return with reciept)
