Check Engine lights and leaking engines and transmissions imply the owner's 
complete disregard for actual vehicle maintenence, or actually more likely, the 
owner bought the car for its looks or 'potential to rice out' rather than 
buying a car that was well taken care of before them.  not only that, but they 
don't put any money into keeping the car in top shape (except for the tire 
silicone and fresh wax) such as repairing these types of things. this is as i see 
it every day at work.  not to say ALL are like this, but a significant 
majority.

On the contrary, you will find that NO body kit or spoiler rice-out 
manufacturer actually claims or offers proof of any actual downforce or aerodynamic 
advantage. in fact, one popular brand even says out right that their product is 
not meant to do these things.

The advance solenoid will receive 12V for energizing at all times, but will 
not cut off vacuum like it should above 104degF w/o a proper ground at the idle 
speed switch (the lower wire on the back of it, should be black i think....). 
 

it is working correctly if the car is hot, at idle, and there is no vacuum in 
the hose that goes to the vacuum advance -on the distributor - .

No distributor on most vehicles made since the early/mid 90's. now it's coil 
packs, kind of like a digital distributor.  the EP-ROM (i think) gives the 
ignition system its timing information.  i suppose when you buy a 'performance 
chip'  the timing is modified to accomodate other changes.

Well here is what i have done to test it, not sure what can be extrapolated 
yet.  

1. Unplugged cold start valve and attempted to start car.  Car starts exactly 
the same way when cold with or without the cold start valve plugged in.  it 
is 50 deg ambient temp and take about 4-5 sec before the engine fires and 
starts. obviously the cold start system is not functioning properly. 
2. checked for clean contacts on thermotime switch and cold start valve.
3. put a meter to the blue connector that goes onto valve and cranked the 
car. when cranking, the meter takes about 1 second to climb to almost exactly 4 
volts, stays there for a few seconds, then tapers off.  does the valve only 
need 4 volts to fire?
4. removed cold start valve and put in a cup.  reconnected electricals and 
cranked car.  absolutely no gas is coming from the valve.
5. reinstalled the plug and removed fuel line.  loads of fuel pressure in 
there so i know it is getting gas.

Based on this information i assume either:
1. cold start valve may have voltage but isn't grounding.  where is the 
ground and how do i test it with a meter?
2. cold start valve internal actuator or whatever is in there is permanantly 
stalled and won't move to allow gas thru when receiving power.
3. thermotime switch isn't putting out proper signal voltage to cold start 
valve. is 4 volts all it needs?

I have an accell performance coil as well as a complete tune-up with Grady's 
parts about one year ago.  in light of the above cold start information, i 
think the valve is the problem, not spark.

Well i know the manual says to open throttle but from what other owners have 
said, if everything works correctly this isn't necessary. i am primarly 
concerned with optimum performance of my car.

yeah, it only took about three years to get it this far (as readers of this 
newsgroup can verify!!!).  once i get this cold start problem fixed, i believe 
it will be about done!

my car idled at 1000 RPM until, as described in my previous post yesterday, i 
had to recrimp the wiring to my idle speed switch (loose wire for ground) and 
i had to remove both set screws for the throttle and put them back in 
properly.  if a mechanic has no idea what he is doing, he/she would probably start 
playing with either the three big brass screws in the middle of the intake 
manifold above the water pump (all should be lightly seated) or they might try to 
play with the throttle stop screws.  perhaps your lower stop screw for the 
butterfly plates is down too far, causing the plates to be cracked and let too 
much air in.  since you didn't do the work yourself, i wouldn't doubt ANYTHING, 
and suspect EVERYTHING!

just keep your cool and check things out one at a time. you will get it!

Subject: Loss of coolant

I just recently picked up VIN 11475 as my first DeLorean.  On the way home a coolant 
hose came loose, while I was on the highway.  By the time I pulled over the temp 
gauge had just climbed to its highest position just in time for me to shut the engine 
off and wait for everything to cool down.  Luckily I had my cell phone and was only 
three miles from a friend with extra coolant on hand.  After I tightened the loose hose 
back on and refilled it with coolant (it took 2 gallons of water/coolant) everything was 
fine, I think.  It there anything that I should be concerned over (other than another 
loose coolant hose)?

Any advice is appreciated!  Thanks!

Jeff

Subject: Re: hard starting when cold?

The usual culprit causing your symptom is the feed to increase volts 
from the ignition resistor when starting. There is a relay mounted 
in the engine compartment on the firewall by the resistor. That 
relay is activated by the starter solenoid and feeds battery voltage 
to the split side of the resistor to provide increased volts to the 
coil during the start phase. Dirty connections and poor relay 
continuity can cause the volts to be too low. Put in a new relay and 
clean the connections. Clean the connections on the resistor too. 
Test the circuit to be sure it is working properly. You may have to 
clean the connection down by the starter too - it is a blue/yellow 
wire connection. It should now start like it was never turned off.

I'm not basing the engine choice on any type of "herritage", or 
anything like that. Imposing that kind of a restriction to either 
keep heritage, or to purposfuly be diverse is actually counter 
productive to the cause at hand.

I'm basing the choice on the fact that it's a commonly used motor in 
Europe for aftermarket engine swaps, and kit car building. Most 
notably, the Rover V8 is usually bolted up to the same Renault UN1 
transaxle that the DeLorean uses. So when it comes to tuning the 
engine, troubleshooting issues with the drivetrain (read: input 
shaft), and even unique/custom installations, a great deal of the 
footwork has already been done for the entire drive train, and not 
just the motor.

Japanese motors are fine, and they do indeed have their place in the 
automotive world. But they are not somthing that I would consider for 
an engine swap, or custom kit car. If I were going to need a I-4 
powerplant, I'd simply stick with a Volvo. Don't get me wrong, 
compact cars are nice. When fuel economy, and close city driving is 
concerned, I like compacts (although I am more partial to Korean 
cars, as opposed to Japanese). They are efficient, practical, and 
entirely foriegn to me. Sure they can be tuned, but why put all the 
extra effort into a 4-6 cylinder motor that offers virtually no after 
market support for custom installations both physicly, and for engine 
management (convert from OBD-II to some custom engine management 
system), and have helluva high costs when it comes to pricing out 
blocks and components (I prefer old fashioned type wrenching, and 
still visit the junkyards when looking for parts)? No thanks. Raw 
power and final output, balanced with installation compatability and 
cost are more important factors to me in a project like this, rather 
than achiving some ideal power=>displacement ratio.

While I was never that deep into it as many people in sport compact 
cars are now. I have been thru that "ricer" phase, and have realized 
just how damn goofy both my car looked, and how I did for doing that 
stupid stuff to it (wheel covers, amber foglights, neon license plate 
frame, fake cell phone antenna, steering wheel cover, windshield 
vinyl stickers, etc...). Now I know how my father felt when looking 
back on those checked pants, and leisure suits he wore back in the 
70's...

So yes, I've been there, and done that. So I can criticise. 
Fortunetly, my DeLorean somewhat "saved" me. When it came time to 
start "modifying" the exhaust, and the cold air intakes, I compared 
prices, and thought of saving my cash to buy a D sooner. Needless to 
say, the DeLorean won out.

So yes, I have respect for true tuners. The guys who truly do put 
their wrenches where their mouths are, and crease some true hell on 
wheels import dragsters. But dudes who simply stop at stickers and 
colored wiring harness sheaths? No, love there. Taking inspriation 
from the office "demotivational posters", my feelings can easily be 
summed up: "Incompetence: When You Earnestly Believe You Can 
Compensate For A Lack Of Skill By Doubling Your Efforts, There's No 
End To What You Can't Do."

No everyone is able to turn their Hondas into bad ass drag racers. 
And there isn't anything wrong with that. But atleast stop pretending 
that your car is somthing it isn't since it still has a stock motor.
