Angry car will not idle.

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

My idle isn't steady either. At least when the car is cold. Does your idle fluctuate when warm too?
Doesn't bother me enough so I just left it alone.

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?

Did you use a timing light to verify you are really at 10*?

i believe so, i went from "using maps" to "fixed timing' and used the timing wizard tool and it was 10* after i adjsuted the + / - till i got "4.00" and i checked the timing at 10* and went back to the sttings and change the fixed timing back to use maps.

try that map and did not do anything good, took a while to start, had to gas it a lot to start and it'll go 1k rpm and drop dead

loaded the old .MSQ
