[DML] Re: Tune-up



The DMCH Nology setup is the best ignition performance kit I have run
across for the DeLorean. I am sure there are exceptions as I haven't
tried all possible combinations but, I have tried a lot. The next best
in my opinion is OEM - with the SILVER spark plugs. I think the reason
most spark systems do not perform is that they are not serviced
adequately. The distributor spark advance systems need to function
correctly and many have never serviced the spark advance system. Spark
plug wires need to be handled correctly upon installation AND espically
removal to prevent damage.

I think many folks suspect ignition problems when the problem is the
fuel system or intake problems. Both systems need to be working
correctly. Unfortunately it takes some proper tools but, most are not
high tech and not expensive. Simple mechanical gauges and analog
electrical tools will be adequate to check the systems. Also, handling
the spark wires with care when removing and installing them is critical
as damage will cause poor spark or other issues.

The position of the distributor allows for moisture to enter the
distributor while driving in rain at speed. Especially in a 5 speed. The
air draft pushes the rain water up against the the bottom of the
distributor cap. You need to put a small bead of silicone gasket maker
around the cap maiting surface to stop this.  Also, the spark plug wells
need to be dry and so, the spark plug boots need to be installed
properly to assure an adequate seal to keep out any  moisture.

I'm looking at John's 25,000 volt Bosch coil [as an upgrade?] since I
doubt the stock one has that much punch to it. I have +4 plugs that are
a little old but few miles and are still in good shape; also Johns 8mm
wires and upgraded resistor. I once used the blaster coil with my setup
but I remember having problems with it - I believe it was melted
distributor rotor but can't remember correctly. Nonetheless, with what I
have as far as plugs, wires and resister; which coil should I be going
after? My engine runs like garbage when it rains, and when it is dry it
sputters at stops from time to time and just doesn't feel "right".
Thanks guys -----Dani B. in FL!
