i wanted to test out my DIYPNP Braineack build.
i fished the vacuum hose through firewall and plug one end to where the cruise control vacuum was and the other end to MS. unplug the TPS sensor, ST_SIG fuse.
the car will start, RPM goes up and goes back down to 0 and car dies out. i try holding the gas down and the idle seems very rough, even though holding throttle at half.
still using stock AFM.
follwed these instructions:

thanks in advance.

got the car running, it was not enough fuel
fuel constants from 5.9 to 11.9
it was set to run 460cc instead of 230cc stock injectors
AIT / CLT set to
F / C Resistance in Ohms
-4 / -20 16150
104 / 40 1150
176 / 80 330
now i got it started i think i lock the timing to 10*
i went to "more ignition options" from "use table to fixed timing" got 10* , burn close
then change back from "fixed timing to use map."
the car idle is not steady from 900-1100K rpm rough idle
what could be causing it?
attach is my MSQ

it's either your AFRs at idle or your idle valve settings themselves
something you could try is changing the idle control to PWM warmup. then manually adjust the PWM duty table until you get a stable idle.
I can't remember, are you using a wbo2?
