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?
