I would like to make a suggestion for you to check out:  Since your
catalytic converter has gotten hot enough to glow more than once, perhaps it
has deteriorated internally restricting your exhaust flow.  Now you have to
dork with your CO adjustment to compensate for the exhaust back pressure.
You might try taking the cat off to see if you still have the problem.  Once
you have it off, look at the webbing in the cat to see if any of it is
melted or broke loose restricting exhaust flow.

Rustproof, How many miles are on the car. Cat's will stop up and 
restrict flow. When this happens it will also beging to glow. If the 
Air flow and or gas mixture hasn't been kept up correct, then the 
cat's can be stopped up. If you do mechanic work, you may want to 
pull off the throttle boby and clean out all the gunk that will build 
up inside. If the butterflies in the throttle body don't close all 
way that too will cause an improper air mixture. David is right about 
the Air Flow Meter and it's adjustments. You have to keep these cars 
tuned. Theres no one computer to do it. When was the last time the 02 
sensor was changed and you say the Lambda System working. Put a can 
of Berrymans B12 in the gas and go drive the car. If there is any 
varnish in the system, it will desolve it.

signal and duty cycle are within normal operating parameters. The 
frequency valve seems to be operating normaly as well. All of the 
extra adjustment screws are seated to allow for the ECU to do its 
job. The Idle control air valve seems to be operating OK and is not 
sticking. No leaks at the cold start valve. The idle switch is is OK 
too. The fuel injectors are all operating with a good spray pattern 
and have been checked for equal fuel distribution. I am running out 
of ideas. Has anyone run into this sort of thing before? Thanks in 
advance for any suggestions you guys may have.....

Subject: Re: Rich Fuel mix with High Idle

I would investigate the cold start system now. It sounds like it is 
not functioning as it is what increases the fuel mixture for starting 
as opposed to changing the mixture screw. Check the wiring and see if 
there is voltage to the cold start valve when the engine is cold 
during cranking. Look for broken wires, disconnected plugs etc but it 
could be a bad thermo-time switch. Refer to D:04:06 in the workshop 
manual.

Brian, A lot of Bosch numbers have a 0 in front of them for part 
number expansion. Some companies tend to drop it. My 2000 Bosch price 
sheet still has the 5 digit #. Oil Filter # 72150 is the correct one 
to use. I'm sure the Mobil One filter is good, but is it worth trying 
if you don't know the specifications for it. The Bosch and others are 
proven.

Subject: Re: Door Launchers

I seem to remember hearing Rob Grady say that the added weight of the door
launcher solenoid will require the torsion bar to be adjusted up another
notch or so.  In order for the system to work flawlessly, everything else
has to be working just right -- the doors should be properly adjusted and
not sticking, the torsion bars shouldn't be over or under torqued, the gas
struts should be of the dampening variety where they don't allow the doors
to bounce at the top end of their travel (unlike the ones currently on my
car.)

Rob's system only uses one solenoid to actuate the door handle.  I have
heard of someone rigging up their own launcher, but it used two solenoids --
one for the door handle and a second to give the door a push off the door
sill.  The two solenoid method might work better on poorly adjusted doors or
with weak struts.  But any extra weight in the door requires that much extra
tension on the torsion bar.

Subject: BTTF/Halloween Question.

[MODERATOR'S NOTE: Since this is pretty borderline, please send responses directly to Robert]

Quick question. Every Halloween we dress up the house for the trick-
or-treaters' that come around. Since this year I'll be home, I was 
thinking about doing kind of a Back to the Future theme. I know that 
others have dressed up their cars/selves before. So my question is if 
anyone can give me any tips on things they've done, ideas for 
props/how to build, etc... One idea I've had is to back the car into 
my garage, and hook up a 12V source to power my clearance and door 
lights (like the casino's use for display cars). I also have a 
question about dry ice. Will the fog that it produces hurt the 
interior of my car? I was thinking of placing a bucket inside of the 
car to let the fog pour out of the doors, but didn't know if there 
would be any ill effects.

If anyone has any ideas, feel free to e-mail me directly off of the 
list.

Thanks in advance!

Subject: Re: Door Launchers

Rob Grady was at the NCDMC/Bricklin show yesterday and talked about the
Door Launchers. The Grady system will work with another Zilla box in the
electrical compartment, and 1 new solenoid per door. You will also need
the Lockzilla module and the Zilla remote (200 dollars each). The new
solenoids work off of existing wiring in the doors, so no new wires will
need to be added from the electrical compartment to the doors. Rob said
the the solenoids he's using weight about 3 pounds each and will require a
slight adjustment to the tortion bars. He's expecting the new Zilla box
and solenoids and compelete installation instructions to run about 600
dollars. Of course it'll be another 400 dollars if you don't already have
the Lockzilla and Remote.

If you've dealt with Bob Zilla or Rob Grady before, you know that every
penny you spend is a penny that they both stand behind. I'm certainly
going to pick up the kit. I believe he said that he's expecting it to
be ready in a month or two.

Stephen Wynne, Don Steger, and Rob Grady all agree that in the next year
we're all going to see a lot of new, extremely cool products come into the
DeLorean world.

I finally put a site together that has the photos I took of the 2nd annual

Subject: Performance intake prototype finished!!

You will all be glad to hear that I have finished the prototype intake I was working on for Deloreans. I will have the pictures on my website soon enough and will keep you all posted as to my progress. As for the intake, I was instantly amazed at how much better to motor was able to breath. The car now was much more willing to rev and felt so much better. The motor is much less choked off and I have found that the car is way faster! For all you techy kinda guys I will have graphs and calculations on flow on my website too. Anyway as far as the intake, I am really proud of myself on this one, it looks great, doesn't require any other mods, it is oh so trick, and works even better. I should be able to start producing them soon if you all want one, but I don't really care if you do cause if you don't you can just watch my tail lights fade! :)

Subject: Re: Re: Rich Fuel mix with High Idle

Thanks for all of your responses! But still, I am up the creek.
The car has only 4900 miles on it and it has been completely restored with
the frame off. It is in pristine condition in and out. The cat is brand new
and clean as a whistle. I removed the original cat that was overheated
(twice) about a week ago. It was clean as well but I had planned on putting
in a new exhaust system anyway for appearance sake. The entire exhaust
system is also new. The throttle body butterfly moves freely and closes
completely. This engine is absolutely clean with a completely new fuel
system. Tank, lines, pump, filter, fuel distributor, the works. No varnish
anywhere.  I can find no vacuum leaks. The O2 sensor was replaced a day or
so ago. Signal from the ECU seems to be OK and the Idle control valve is
functioning with a normal duty cycle. (except during cold startup when the
sensor is ignored by the ECU prior to 350 degrees warm-up sampling) The
thermo-time switch seems to be doing it's thing. When the CO mix screw is
set so the engine runs at 950 rpm at idle, there is no overheat condition.
When this baby is set to idle at 950, there couldn't be a sweeter running
engine. (no exaggeration) Smooth, VERY powerful and responsive.
Unfortunately, once I shut it off.....it doesn't want to restart. Today I
will tear out the cold start valve and see what might be awry in
there...Stay tuned.

Subject: Battery master switch?

Hi All, 

  Hope everyone is enjoying the final weeks of good weather driving! 
After reading that poor fellow who lost his car due to a meltdown, I 
started thinking about a battery master switch again. Does anyone 
have any suggestions for a cut-off unit with a remote switch of some 
sort? I do not care if I lose my radio station programming :-)

  I though I saw a unit that will cut the battery supply VIA a remote 
toggle switch that could be located anywhere in the car. That sounds 
good but I can't remember where I saw that.

  Any other suggestions? I just can't see myself with a wrench 
unbolting the positive every time I finish driving it! Anyone know of 
any adverse effects for repeated battery dissconnecting?

Thanks!
