My 03 ascender has an acceleration issue it does it every now and then usually once I go from a complete stop sounds like it wants to cut off.

This sounds like the Idle Air Control Valve. This is located on the throttle body, and it controls idle speed and the fuel/air ratio when the accelerator is disengaged. Another problem could be loss of fuel; try changing the fuel filter and having your fuel pump tested for proper pressure. If that's not the case, try checking your Fuel Pressure Regulator. There are a number of things you can do, but since you don't seem to have a Service Engine Soon Light, it's difficult to diagnose the problem.

Check to make sure you installed the fuel filter in the right direction for flow, if the vehicle was working fine before hand then your problem is located in something you replaced, if not have the fuel pump checked for flow rate it may be starting to get weak and needs to be changed.

When accelerating, my speedometer goes in reverse.

I would recommend you try to perform a fuel system pressure test. The specifications are available by calling the dealer. It seems you have a fuel delivery problem, possibly a bad fuel driver module or pump and that is located in the fuel tank. Follow the precautions when performing the test. If you hard accelerated and the vehicle stumbles or has a "dead spot" on acceleration then it's a good indication that it's a fuel delivery issue. The reason for the speedo going wacky is because the vehicle is not performing properly !!

The engine runs as long as you maintain pressure on accelerator? The most probable cause is a clogged fuel filter. Once the filter becomes clogged, when you release the accelerator, there is not enough fuel pressure to maintain the proper amount of fuel through filter. Have the fuel filter replaced and that should clear the problem.

When accelerating there is no power but when releasing accelerator slowly power picks up. why is this happening 2001 ml270 cdi

Hi, this is a common symptom of a clogged fuel filter that is straining the fuel pump itself.

When you accelerate, this initiates a rapid fuel flow through the lines. if the filter cant pass the proper amount, its will stall or hesitate the engine and cause sputtering or loss of power. due to this clogged filter, the pump cant keep up with your acceleration demands at this time. the reason for the power pick up upon De acceleration, is because the lower amount of fuel is able to pass through quite easily but, as soon as you demand more power, the clog will obstruct the more intense flow of fuel to the injectors.

Simply replacing the fuel filter and pump will fix this issue.

Please rate and god bless:)
