You need to find the vacuum leak. It is going to be anywhere from the
mode switch on to the hoses and actuators. Start with the mode switch
if it hisses.

Sounds like a voltage drop in the primary coil voltage. The
connections going to the voltage resistor and coil need to be
cleaned up. Put some "bulb grease" on the connections after you
clean them real well. Clean ALL of the connections. When I lived in
Houston I experienced similar problems.
If it just happened when driving I would say you need to put some
silicone on the back side of the distributor cap. Driving in really
heavy rains would always spray lots of water on the distributor cap
and moisture would get into my distributor cap. The location of the
cap is such that the rain spray is like spraying water up on to the
underside edge so, without seal water gets in.

My engine has been tapping recently at idle...and I have a sinking
suspicion its a rocker arm. I want to know if anyone on the list has
had any experience with shops in MD with this kind of work. I am
located in the Frederick area and work in Rockville (near DC).
Thanks,
Bruce Duncan

That would certainly be an awesome sight... but remember, they must all
face
FORWARD! Some of the list members have had their cars damaged by
backwards-faced towing.

Idle motor "sticky"; check the connections. The fuel mixture could
be changing drastically by the frequency valve. Check for vacuum
leaks. Check for a clean connection at the frequency valve. Also,
the oxygen sensor could be going bad on you.

First, I would check for water in the plug wells. If water is present it
does not burn off like you would think it should. In any case, you need
to
get something down there to check for water before you try and remove a
plug
because the last thing you want to do is let water drain into the cylinder
(I used a lint free paper towel and a small screwdriver).
Next I would consider a major tune-up. Any vendor can supply a kit. I
could be caused by a breakdown of plug wire insulation.

Subject: Re: Clean the fuel tank?
I had to take care of a few more things before I could start my
Delorean up again (I just turned it on for the first time in the
better part of a year today). Your advice helped save me some time,
though. I ended up leaving the less than half tank of gas in the car
without adding anything to it or draining any before starting.
Although the car was stored outside in Maryland for about ten
months, including winter, the gas still smelled like gasoline, the
car started fine, and everything seems to be in order. Thanks again
for the advice.
