everytime i fill my tank right up my car seems to die a little bit everytime. It is normally quite a nippy car and everytime i fill up it seems to die down and it takes me ages to build up speed, but once i get down to about half a tank it seems to come back again. any ideas???

strange one! could be that there's a lot of muck in the bottom of the tank getting stirred up when you fill up and temporarily blocks the filter or it creates an airlock somehow, i don't think the weight of a tankfull will make much difference, even though just one gallon's gonna weigh ten pounds. Re-post in the car section,CDC might know.
