Hi all.

tonight on the way home my car started messing around when i put the aircon on.

It feels like it was missing slightly,then it clears then it messes about again and then it clears and so-on.!!

But when you turn of the aircon it isn't so bad.

So i am wondering if with the extra load on the engine it is missing (spluttering).

I have checked the spark plugs recently and they seem ok, Could it be the leads??

Any advice would be gratefully appreciated.
