Question
THE CAR STUMBLES A LITTLE WHEN IDLEING, AND WHEN I TRY TO GO UP A HILL IT STARTS TO BUCK REAL BAD BUT IF I RELEASE THE GAS PEDAL AND GET BACK ON IT REAL QUICK IT DON'T BUCK I WAS WOUNDERING IF ONE OF THE CRANK SENSORS ARE BAD AND COULD BE CAUSEING THIS PROBLEM AND I BELIEVE THERE IS TWO OF THEM IN THIS CAR.THANKS RANDY

Answer
Hey Randy:

it could be a lot of things. But a crank sensor is not really liekly. I would be more inclined to think a bad ignition wire or coil pack cauing the issue. More so a wire or even a plug. I have seen where water/condensation had collected under the plug wire at the engine side and the water cause a misfire on on of the  cylinders pluug the wires out one at a time and see if they ate wet or have a rust loot to the end of them if so you found the problem. another though would be a fue issue either a plugged fuel filter or a pump that's loosing pressure. Just a few things to look at. Good Luck :)
