Ford Repair: 1995 voyager van, throttle position sensor, air control valve

Question
i know its not a ford but it could be a problem with any vehicle.  my van when you start it up the whole van starts shaking, the headlights are on but flicker a little bit.  and when you try to give it gas it doesnt do anything unless you floor it.  any ideas

Answer
This can be caused from a variety of problems.It could just need a tune up.Back track to when it started unless it's been doing this for a while.Try cleaning the throttle body and idle air control valve.The throttle position sensor could be bad.You said that this could be a problem with any car,but I have never heard of a Ford doing this.The best thing for you to do is to check to make sure that the firing order is right,clean sensors like the two I previously had mentioned along with the EGR valve.Also,check the ignition timing.It might help if this is sensor related to have the engine codes read.
