Message MODS:
660cc Injectors
EGR delete
Adjustable FPR (set at 40psi +/- 5 @ idle)
FMIC
SAFC2
AVCR
E-mance chipped ECU (supposedly custom base map for my setup)

Here is the problem: The car starts, it starts with a little bit of issues and usually needs a little bit of cranking but it starts every time I try. It idles 900-1200 RPM as it warms up and then settles at about 1000rpm (which is high, FSM says 700rpm for idle). The vacuum at idle when warm is steady at ~17inHg. If I hit the throttle and stay on it, it will try to rev but then it dies every time. If I tap it quick and let off it will drop to ~400rpm then bounce back up to ~1500rpm and then settles out at ~1000rpm half the time, the other half the time if I held it open a split second too long it dies. I have tried setting my SAFC to -40 on LO throttle from 800rpm to 3200rpm. The injectors are at 1.2 % at idle and when I flick the throttle they will jump to 100% or more and then back down to 1% - 2%, The voltages all look normal, all the injectors ohm out perfect, the TPS shows .4V - .6V at idle and 4.5V - 5V at WOT (with ignition on but car not running). The ECU randomly throws a Code 13 (Coolant Temp Sensor) this code comes and goes. I dont think the Code 13 is the reason for all this nonsense but I guess at this point anything is possible. Sorry for the novel guys but I'm at the end of my rope please HELP!

Thanks in Advance
Anton
