Idle fluctuations, heavy vibrations, sputtering, loss of power - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Recently ive been gettin idle fluctuations that would go away after like 5 mins of driving, I thought maybe it was a dirty iacv, but yesterday I was driving home from my friends house, the fluctuations were there the whole time back, the car was vibrating hard, there was a loud sputtering coming from the car/exhaust as I would press on the gas, and it felt like there was a loss of power in the car.

Could this be a bad injector? Or maybe a bad spark? I put in new spark plugs, but foolishly kept the old wires. Any advice would be great. Oh and its a 91 240sx KA24DE.

change the wires. Keeping the old wires is foolish since they don't run too much. and if you want to hear for a faulty injector, get a metal rod (I find that a metal car antenna works great) and put it to your ear with the other end the injector. A clicking means it's pulsing and working.

Thanks for the advice man, after inspecting the wires and injectors, it turns out its the injector for cylinder 3. I have been having trouble finding 240s at the junkyard, anyone know if the injectors from a ka24de altima will work as a replacement?

Yeah. They're the same injector.

No problem :].

Some douche took ALL the altima KA injectors at the yard this weekend, but got lucky and found a set in a G20. Swapped out the #3 injector did some cleaning, put in new rubber fuel lines on the fuel rail. Car runs great now, very smooth right at start up.
