Last night I noticed at some lights that she felt and sounded a bit lumpy on idle. Revs were missing a beat and I could feel the difference through the seat. A quick badly sounding rev later and she was purring normal again. Got home and nothing strange.
This morning I was sitting idle picking up a friend and it did it again. I got out the car and could hear the difference from the exhaust again. Revving slightly didn't help so I turned the engine on and off which worked. Then at a roundabout it did the same thing! Couldn't switch off and on so I was driving with it. The car was not giving 100% until about 5 mins later when it suddenly kicked in under acceleration.
Now I am getting worried, what do you reckon?
EDIT: Nearly forgot its just been serviced and has new spark plugs. Not getting a warning light and temps look normal. Revs don't seem to dip with it either.
