fuel or electrical

Asked by Jul 14, 2010 at 11:57 PM about the Ford F-150

Question type: Maintenance & Repair

when i pull out of drive way and start up a slight grade my truck cuts out or misses,if
i accellerate it will take right off and run smooth,it doesn,t do it all the time and its
worse sometimes than others,just had new plugs put in and injectors cleaned,and new
fuel filter and air filter,also a new fuel pressure regulator nothing has coded up,it
might be my imagination but it seem to do it more with ac on than when its off,could
it be the fuel pump or mass air flow sensor,can anyone help me
