Is this a Crank Position sensor Problem??

[LDusky]

Some times, not all the time, when I first take off the engine stumbles at about 800 rpm. If I go to neutral it goes away. Today 1100 rpm was as much rpm as I could get for about a block then it started to drive normal. Is this a Crank position sensor problem?

Mine did the famous stumble and DC replaced the fuel pump and the MAP sensor... seems to corrected the problem.

Frank, Thanks for the reply. My lift pump is ok. Like I said it is not happening all the time. Can't figure what the problem could be.
