Hi, my name is ***** ***** I will be happy to assist with this today.In some cases, I may need more info to assist better.I apologize for any delay.

A fault with a lack of power and acceleration can be caused by a weak fuel pump/injection pump or an issue with a restricted fuel filter.These two are the most common causes I have seen.If you have not had the fuel system tested at all to see if this is a lack of fuel to the engine this needs to be done.If this is or was done and is found o.k. the next thing to have checked is the exhaust.If you have a restricted exhaust component like a restricted catalytic converter or muffler or resonator this also causes this issue here.An exhaust back pressure test would need to be done to see if a restriction is a cause needing repaired to resolve this fault.

These need to be checked into to locate and repair this issue here.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service, your 5-star rating is appreciated ( should be a link to click on here or above).You can rate at any time and we can continue to work on your question as this will not close out your question.I work on delivering the best answer and help here but in some cases, it can be difficult to do without seeing the vehicle.

Thanks Pete
