86 Esprit Turbo Engine Stalling

[ksoufi]

Greetings, I just purchased a 1986 Lotus Esprit Turbo with 61K miles. The first four hours of driving this car were a blast. I felt like a kid again. Then something went wrong. If I release the throttle, the RPM goes to idle speed (around 1000) then the engine stalls. I cannot re-start the car right away. I must wait for 2 minutes before the cars starts again. I was able to drive the car back home, but with difficulty since I had to make sure that the RPM is high enough so that the engine does not stall. I also smell strong fuel smell in the car while driving home after the problem occurred. While driving the car back home, I noticed the following: under 3000 RPM, the engine is not running smoothly. Under acceleration, the car first shows signs of too much fuel in engine, hesitates a little bit, until the turbo kicks in and the engine RPM reaches 4-5k, the problem disappear and the car accelerate like usual. Is the problem due to faulty ECM or Fuel By-Pass? Any suggestion? Any suggestions on where I can order parts (other than the dealer)? Also, please let me know if I can post your reply on a web page dedicated to this problem (which I will setup very soon). Thank You

Thanks Juddy. I too had a faulty relay. I replaced it but that did not fix the problem. For now, I adjusted teh throttle cable so that the RPM is over 1500. The next think I am replacing is the Oxygen sensor. I will let you know if this fixes the problem. Karim
