after the car is in closed loop
the car cannot maintain idle it keeps dropping rpms and will stall eventually
also if i hold my foot in the same position at any rpm it will drop rpms and sorta buck than will sudden gain back all its power and fly for a couple second until it does it again

i have tested this on the optispark ignition and the delteq ignition
it does the same thing

tried using my fuel pressure tester but can get a reading at all
maybe the shrader valve is busted?
car runs and starts like a champ

all input and any test i can perform is appreciated

Does "Born again" mean it was recently rebuilt? Is this your first time starting it up? Who did your tuning?

 

hah i been struggling with this car ever since i swapped out the v6 in the middle of 2004
i had bad main bearing that made the car feel like it was gonna vibrate apart so i had it rebuilt and now i cant get it to run right.
