sr running rich, shit idle, no power on boost

[Steve_S14]

so i was driving the sr around, and all of a sudden it started running like shit, the idle is rough, it smells like its running really rich, the injector, im not sure which, is making a loud ticking noise compared to the others, it almost stalls out after being revved, and if you feel the fuel return line right next to the FPR you can feel the fuel being pulsed through at the same rate of the injector ticking noise.

at boost, there is next to no power and if you try and hold the throttle down hard it backfires like a mofo. could possibly blow out flames i dont really know (cant see the ass end while i drive).


im thinking that either the fpr is fucked out, but more likely one of my injectors has bitten the dust, has anyone experienced something similar?

i also noticed that when i remove the oil filler cap from the valve cover, it smells like there is a bit of gas mixed in..


i filled my tank today with 93, could it be bad gas?

Most likely a boost leak.. double check/tighten your couplings on all the intercooler piping.

Boost leak...........

theres gas around the 2nd injector from the firewall and a bit on the fuel rail, it seems that the o-ring is indeed bad

i tried removing the 2 screws from the injector cap but they wont budge and im worried about stripping them, does anyone have any tips to getting them out, i tried wd-40, but i dont really want to heat with a torch because of the fuel leak and fuel rail etc all in that area.
