any ideas?

my 95 4.9l E40D has a flat spot when taking off. It is a small/tiny lag but there non the less. It will do it when in park and at idle...if you try it several times in a row and let it return to idle each time it will go away but returns. Sometimes it is more pronounced when leaving a stop light. Kinda wondering if a vac leak could cause this.Iit runs very good with out any other problems. It has 130k.

does your blower go from floor to defrost while your hitting the gas?

octaneforce, wow, you caught me by surprise. I did not splain my self...it's the engine idle that has the flat spot and it'e been cold here(freezing) around 32* but my blower never changes. I'm not understanding your question or direction?? But I am willing to hear where your going!after some thought...I can't answer your question even though I ahve been using the heater...I never noticed>

Good thought octaneforce! Could very well a leak from the vac line that controls the blower controls.
