Just to update this thread. Just got the car back from the transmission specialist who had confirmed the torque convertor was on its way out. I had the whole box overhauled due to the millage - 133K, and she is as smooth as silk now. Thanks to the guys on here who pointed me in this direction, without you I would have still been chasing that miss fire ! Not that I didnt have one cause I did, caused buy me buying cheap coils to try and cure a miss that wasnt there !
