Hi, good evening, my car is the GS model. It is giving me problems when the engine is still cold. It will start but it will not function properly, it will start shaking especially when going up a hill. We have checked the plugs and wires and changed one, but still we are encountering this problems. Once the engine heats up the shaking stops. Can you give us any suggestions? Thanks for your time.

Change the rest of the plugs and wires. At that mileage, if they have not been done yet, then it is overdue. Also, the wires can look fine to the naked eye, but the insulation could be wearing thin and allowing sparks to jump from one wire to another and from the wire to any piece of metal that is grounded to the frame (most of the metal in the car is grounded in some fashion). When the engine warms up, it does not need as strong of a spark to run well, so it runs a little better after it warms up.
