Mini cooper juddering

[Bungle1]

Hi there. I have a Mini Cooper on a 04 plate, my mini started to judder under load so i have changed the spark plugs, but vehicle still judders, and Before i start to hand over money to garage can anyone help me with this issue.

You probably need to elaborate a bit more on the judder.

As Eviltad says we need more information, but for example it could be related to the plug leads, the engine managment system/sensors or even that you bought/were supplied with the wrong plugs (happened to me recently with my daughter's Clio).

Should be one of the following

• spark plugs
• Leads
• Coil pack

All the above cause that fault without an engine management light, start with the cheapest but it will most likely be the coil pack
