Hello my name is ***** ***** I will assist you. Normally the symptoms you are describing are due to the engine going lean. This is normally due to either a low fuel pressure or dirty injectors that would require cleaning. First thing to check is that there is 38 psi fuel pressure on the fuel rail, if that is ok then you would need to get out the injectors and clean them. I am assuming the fuel filter is clean, if it has not been replaced start with it.
