Hello everyone,

I have a concern regarding my 240sx. Seems as though the problem comes from what I thought was an empty tank of gas but Im not certain.

Basically I was driving home one night and my tank was quite low on fuel however the light had not yet turned on. So i kept going home, right as I passed the gas station the exhaust started fluttering as if though I had a massive misfire. I didnt really ignore it but figured I was out of gas, I noticed that my RPM's were dropping immensly and... Well the car died on me and I added some gas yet it still would not start. Figured the lines had air in them and needed to be aired out somehow.
Next day, I went to start the car and ran fine. A day later when I was running out of gas again I felt a similar jump in the engine and a backfire out of the exhaust. I made it home and figured id pump gas the next day. Filled up the tank the next day and the car still bogged out on me. It would not give in.
Seems that it will run ok when it wants to or something like that. I went to Nissan and somewhat explained the situation and they told me it would surely be the injectors because this happens so often on KA24's. Is that the case? If so, is it as easy as changing out the injectors or could I clean the ones on the car now?
I started the car this morning, the engine runs fine past idle but at idle it vibrates really bad.

Any ideas? thanks in advance.
