Hello fellow S2K members, I have a serious(hopefully not... ) problem with my car. I dont know if this thread is approporiate for this section or UTH section, but here is my problem... I've had basic comtech supercharger with aftercooler out of the box for more than a year. Today, for the first time, when I tried to start my car, it cranked up and start as usual, but suddenly died during idle. No hesistation, sputter, or any abnormal signs, but just died. I tried to get my car started couple of times, and it finally stayed in idle for mayby 3 seconds, then died again all of a sudden. Again, no sign of abnormality. Car just shuts off as if I took out my key. After third try for my car to idle, it was fine again. After i got home from work, I turned the car off and tried to start it again. Car dies again. I tried searching since I remember reading about this symptom from this forum, but search is . Can anybody help me with my problem??? Sorry for such long post, but I'm worried that something maybe wrong with the car. Thank you all in advance for reading this post, and I appreciate any comments/recommendations/feedbacks.

 

Sent a reply to your PM, but I will also comment in here as well. When my Comptech Setup was new I had a similar problem. Mine was merely causeed by my fuel pressure regulator being turned up to high and spark plugs gapped way to small (30)
I had similar symptoms when i started my car it would have its normal high idle, but once the car warmed up & idle went down it was be bouncing around between like 1-2bars & 700ish rpms. Once I revved the motor it would drop all the way to 1-2 bars & cut off. To fix the problem I put new spark plugs gapped to 33 on small side 35 on large side (circular gapper). Then we turned the fuel pressure regulator down, ever since car has been running fine!

Hope this helps.
