Loses power on acceleration and on an incline. I can go along 100Km/h and when I come to an incline it loses power and begins to shudder. Could plugs cause this. Any other ideas would be helpful. Thanks

Hello,

It sounds like you could have plugs that misfiring under load (acceleration).

Typically when the plugs gets old and have carbon build up they can misfire under acceleration.
Inspect the plugs for wear and gap. The correct gap is 1.1 mm (0.043 in).
Replacing the spark plugs are easy to do. You will need a correct size spark plug socket and an extension.

Thank you.
