My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.My info is somewhat limited on your model here but I had seen no one else has responded and would like to see if I can help here.If at any time you feel that I cannot help with this please let me know.

In allot of cases restricted exhaust can cause an issue like this here with the restricted exhaust component needing replaced to correct this fault.I have seen a plugged catalytic converter or resonator cause this as well as a restricted muffler.If you have not had the exhaust back pressure tested at all this needs done.If there is excessive back pressure in the exhaust the restricted exhaust component will need replaced to correct this fault here.If this was already checked and found to be o.k. let me know so we can continue.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete

The only other issue I can see here that will cause a fault like this is low/weak fuel pressure or fuel volume due to a failing injection pump or restricted fuel filter needing replaced.I have also seen issues with debris in the fuel tank cause an issue like this here needing cleaned out to correct this fault.This will have to be checked into further possibly having the fuel system tested to see if any issues are found with the injection pump or possibly debris in the fuel tank needing corrected here.

Let me know if you need anything else and feel free to rate my help.

Thanks Pete

Have you had the fault codes checked at all to see what codes are set and if so what codes are set if you can post them here?

Let me know,thanks Pete.

No fault codes at al. Computer say no probs

If you can check the engine coolant temp sensor data and see if you have a faulty reading engine coolant temp sensor causing this issue here.I have seen faulty engine coolant temp sensors in the past before cause issues like this here needing replaced to correct this fault.

Check the throttle air inlet bore into the engine for any carbon build up and if any is found or any debris found in it this will need cleaned to correct this issue.

If this model uses a turbo at all there is a chance that the turbo itself is faulty.If the turbo has failed it will not create any boost pressure and causes this acceleration/power feel like you see here as well.

One last thing that will cause this is if your model uses a mass air flow sensor if this sensor is sending an incorrect signal of air flow to the computer this will cause a lack of fuel or over fuel issue and cause this issue here.I have had to replace several mass air flow sensors in the past before for issues like this here.

All of these need checked into to see if the fault can be located and repaired here.

Thanks Pete
