fuel injection issues

[bradartigue]

OK still having issues with my fuel injection. I have replaced all lines from fire wall to everything else in engine bay. i just rebuilt the dissy. also replace sensor on radiator tee and pig tail. all to no avail. still runs good when running but if i come to a sudden stop the motor will stall out or if i rev the motor under the hood it does the same. when running good idles at 1200 perfectly every time. how ever since i did the 2 repairs it seems to have got worse. any ideas ?

1200 RPM isn't idling, it is running, and probably because your TPS is out of whack. Test every FI sensor and get your idle bypass screw and throttle position screw in the right positions. I explain the procedure: http://www.artigue.com/fiat/tuning-book

I have always been curious as to when you should adjust this screw. Would it be best to verify once car is warmed up? Will it not effect the idle when cold? Mine currently idles at 800-900 rpms when warmed up however, sounds like it wants to give out when first started

Warm. When cold the car idles off of this AND the AAR; you can't adjust it properly with the AAR open.
