Engine Help $$$$

[scott-c-arnold@xxxx]

Since shortly after I purchased my DeLorean back at the end of 
September, I started having engine trouble. It ran fine during the 
test drive so I even drove it home from Chicago to Missouri. 
Sadly, one of the reasons I bought it was because it ran well. At 
least it lasted for the trip home! Since then the engine has had 
trouble idling and won't accelerate -- The engine will not idle when 
cold, and the engine tries to cut out and die rather than speeding up 
when the accelerator is pressed. The problem seems worse when the 
engine is cold, but now I can't get it running long enough to get it 
warm so that I can double check. When it is completely cold, it will 
start and run great for about 5 seconds and then it dies. I can hold 
down slightly on the air metering flap and it will idle. 
Unfortunately, once the engine gets luke warm, if it dies then it 
won't restart. At this point, playing with the air metering flap 
seems to have no effect. The last time I was actually able to get the 
engine completely warm without killing it, it ran fairly well; it was 
drivable. I have fuel pressure sending units hooked up now and the 
fuel pressure (both primary pressure and control pressure) look fine. 
The primary was about 72psi and the control pressure slowly climbed 
in pressure at a rate that appeared to be in spec with what is printed 
in the workshop manual. I also have a new control pressure regulator. 
With the correct fuel pressures, the initial push-on-flap-for-idle 
problem suggests maybe a vacuum leak. However, this does not coincide 
with the luke-warm engine no-start problem. I'm stumped. I can't 
imagine what would cause the symptoms I am seeing. Perhaps I have 
more than one problem? Having just spent around $16000 for the car 
and various parts in the past 1 1/2 months, I only have about $1500 
more I can spend to get the engine running again. Is this enough to 
send the car to DMC Houston? Anyone want to stop by Columbia, MO, and 
get my engine running properly for $1500? I might could swing $2000, 
but it would be difficult with X-mas coming up soon. I HATE fixing 
these types of engine problems! Help! I have already put 
probably one hundred hours of work into this and other problems so 
far, and I was hoping I would actually get to drive this car some day. 
After $16000 and 100 hours, a pretty garage ornament is just not 
satisfying. I am beginning to think maybe I should have just bought a 
Corvette! At least I would be driving it by now! Anyone have any 
advice?

Thanks,
