A couple days ago, I went to start my s14 ka and let it warm up. After it was warm, I went to move and it started to jerk and the rpm would bounce up and down. I would put it in neutral and it would idle fine, but when I would go to move it would start to jerk again. It stopped after maybe a mile a slow driving like that. I checked the spark plug wires and unplugged and plugged them back into the motor and when I cold started it, it did not jerk or anything. Does anyone know what is going on? I was reading it could be the fuel pump or MAF but I'm not too sure
