4.6L Hesitation from a stop...

I have a 99 Expedition with 131K on it. Lately it has been stuttering or hesitating from a stop. Almost like its starving for gas. It does it for about 2 seconds then fine. Doesn't do it all the time, but its worse when its cold. Other than that runs fine. No check engine lights. Plugs and wires and in good shape.

Any ideas?

Try cleaning the MAF.

https://www.ford-trucks.com/forums/s...hreadid=126093The ones in the 97 and up trucks are accessed a bit differently...you remove the air cleaner housing as if you were replacing the filter and then you can see the MAF inside the big hose that goes to the Throttle Body.

If cleaning the MAF doesn't work, it could be a bad TPS sensor.
