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, Scott Arnold
