1996 Jeep Cherokee

When pressing on the gas feed to accelerate the engine seems like it trys to stall while doing this the rpm needle while jump as if you tap the neddle and it rises and falls back it will only do this when you ecelererate at 1/2 throttle it is like a missfire but its not you also here a clicking noise from under the dash on the drivers side it does not leave any codes it also does this if you are driving 50 miles an hour and try to acellerate and some times while just trying to keep this speed
