I just tightened that injector a little more so the bubbling stopped but is still the same. The throttle seems very touchy down low and seems to work normal at higher rpms. The surging is only from 1100 to 1200 rpms. When you bring the throttle back far enough to get them to drop from there it slowly kills the motor. Just before it dies I push the throttle a little more and it will rev up to around 11-1200 then come down to normal idle. Also i wanted to add it is still hard to start cold. It was above 0 degrees Celsius today and still needed glow plugs cycled 3 or 4 times. After it starts it will start right up Every time after that, but if it sits 15-20 minutes it will be hard to start again and needs the glow plugs to start.
