Surging is the condition where the engine power fluctuates up and down with a continuous, soft jerking motion. When driving at a steady speed, the engine seems to speed up and slow down, without moving the accelerator.
its run on road for 5 min then rpm fluctuates and quit, seems when engine is warmed...and will not restart till cool down.
2-stroke engine
The combustion cylcle (power stroke) forces piston down to create engine power.
Signs of turbo going out are engine power is down or engine smokin oil leaking from turbo turbine shaft seal into combustion Chamber
its between the fire wall and the engine. down about 12 inches
Could be an engine power problem or the hydraulic pump is not sensing the load and could be trying to absorb too much power.
The power stroke. The order is intake, compression, power and exaust. The piston moves down on intake and power but is only forced down on the power stroke
Probably not a good idea, your power steering and power brakes will not be functioning.
On the passenger side of the engine about half way down inside the engine compartment toward the front of the engine compartment
Aside from a complete tear-down there is not much you can do. Regular oil and filter changes can help prevent that condition.
Down the bottom right of the engine bay!!
You are going too slow...... Having large tires will cause the available power (because of the high ratio) to not be enough to turn them. This assumes everything else is in reasonable condition and there are no 'problems' with the engine, like a cylinder misfiring or low power output.
