Hey guys im having a little problem here i have a 95 s14 with a KA-T im currently at 10 psi, with Je forged pistons and rods and built head... im getting a cel for knock sensor, rear o2 sensor, and 21Ignition signal in the primary circuit is not being entered to the ECU during cranking or tuning
now i just changed my plugs and decided to reset the ecu and now while im cruising or idling the cel light blinks. there is no real pattern its juts off and on constantly does anyone know what this means? what does the cel 21 mean? and does the knock sensor show a light when it is faulty or when the engine is actually knocking?

Thanks to anyone that can answer any of my questions!!
