2000 F150 runs perfect some days, then will buck, cough, shake and stall.
Had two different techs look at it payed over $1000 between them still the same. Weather has no effect. Fuel type has no effect. AC does make it worse. Driving slow (parking lots) and stop lights it gets bad....stalls. I need to put it into "N" and give it gas. Now again some days it runs perfect....tryed all kinds of sensors, throttle body clean, you name it.
Was told it may be the intake gasket, but wouldn't that be a problem all the time?

Help!!!

 

I've got the same thing. Almost seems like an intermittent fuel pressure prob since my pumps run constanly and won't shut off unless I turn the key off. Also won't run when that happens. Pumps are supposed to run for a second or 2 and then shut off. I'd give anything for a carburated engine right about now

 

Could you be having a fuel pressure regulator problem? I think if it was electrical it would be constant where a regulator could be intermittent. Just a thought.
