can you help a brother out on why I need to have a vacume leak to keep the car running?
J9fd3s you got aim?

Your telling me no one has been able to help me on this. Some said to adjust the variable resistor. Some said some other crap IDONTKNOW. Mabey the 5/8th inch fuel lines? Mabey the ECU is fucked. It is running shirt rich im getting like 8 MPG who knows.

To my knowledge...S4 injectors/harnesses/ecu all use the same impedence, so swapping that stuff around isn't causing the problem..
I don't recommend driving the car w/ the secondaries disconnected...u may lean out and actually blow the motor(if your not VERY careful)...
..the lumpy idle is probably caused by the vac leak itself..I dont know ur entire setup, so I can't explain the MPG..nm, u just IMed me...I'll talk there now,lol...

86-88 is low impedace, 88.5-91 is high impedance.
86-88 injectors require a resistor pack because every fc3s ecu will only run correctly with a high impedance injector signal. Find out EXACTLY what year ecu you have, either 88 or 88.5. As said secondary injectors only come on after 3800rpms UNDER LOAD, not while revving in nuetral.
You must plug in the pressure sensor. It has nothing to do with FUEL FYI. A vacuum leak will raise your idle, maybe thats why it will keep your car running? If you variable resistor still has the stock protection stuff in it( some kind of coating or rubber filler to keep owners from messing with it) then thats not your problem. If it has been messed with, then maybe you shoudl try adjusting it. 5/16" fuel lines??? Thats not anywhere near the problem, whoever told you that has their head buried in their ***. Vacuum leak or bad/misadjusted tps could be the cause of your "lumpy" idle. And please reread your damn posts. I've had 15+ shots of hard L tonight and I my post still make more sense than yours.;
