Hi I am new to this site and have a problem with my truck.

When depressing the throttle quickly the truck stalls and also has erratic idle.

Have changed plugs, plug wires, cap, rotor, pcv valve, air-filter.

Also has lost power climbing hills and am getting bad gas mileage.

Today I could smell and hear a small exhaust leak. Don't know if it is the manifold or maybe the donut gasket??

If anyone has any suggestions in what to look for and how to fix this problem it would be much appreciated.

1995 F150 4x4 302 engine

Thank you

 

since i have been waiting 4 a reply i investigated further seems when idling if i depress acclerator while in park sharply it almost seems like it gets flooded will either stall or idle rough until it recovers from this action if any advice out there would be greatly appreciated thanks in advance

 

Check your fuel pressure and get back to me as to what it is with the vacuum line on and off.
