[V8] V8 problems go on - ignition rough running

[Moy, Bob]

Use an ohm meter to check the wires.
Coil wire resistance should be  2000 +/- 800 ohms
Ignition cable resistance should be 6000 +/- 1400 ohms  

I also had a similar problem serveral weeks ago (no power and the the engine
missed and backfire) turn out to be that I needed to replace distributor
caps and rotors along with a blown ignition coil module.  Smoke was pouring
from behind the left cylinder.  

The rotors was a set screw type and I ended up reversing the rotor 180
degree.  Felt really stupid after discovering what I have done.  Reset the
rotor to the correct position and the car runs fine once again.  The cap can
be removed with either a screw driver (two screws) or a 8mm thin wall
socket.  The distributor is held by two bolts (10mm I believe).  The
original rotors were glued on and I just use a visegrip to crack the old one
off.

Hi All,

Thanks for the help on the starting problem - rpm and crank sensor. It 
starts well but  now it  runs rough and misses/backfires. The shop said 
it needs new Dist. caps and wires (ouch)! I pulled the caps and cleanded 
up the contacts - did not help. Do you think the wires are it? Can a guy 
make his own set vs the $300or so  for wires. Should I be looking at 
something else? The rough running was not a problem prior to the rpm and 
crank sensors.  Also it seems to shift harder now - more abrupt.

Thanks,
Greg
