Sr20DET running rich: idle, timing question and fuel injector pulse question - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Ive got a s13 redtop (first gen = no heat sinks) in an s14
running stock t25,
stock sidemount,
nismo FPR,
apexi twin chamber bov,
stock elbow,
stock downpipe and cat
and a 3" URAS catback

the car is running very rich and idles high at around 1300... i cannot seem to get it to go lower than that with the idle set properly, when i do the timing has to be all out of wack.

when i adjust the timing to 15, and rev the motor, it stays at 15 and does not move, is that normal?

also im unsure, but i wanted to know if the fuel injectors are continuous or if they are pulsed, and if anything other than just the computer will effect them.

i looked for an idle adjustment on the manifold near the iacv but i was unable to find one.

can anyone help me?
