I started my car for the first time in about two months started ok but died shortly after if i give it some throttle its ok but with no throttle it dies my petrol is almost down to the red but isnt quite there would that be the only reason it does this?
Try cataclean, cleans out most of the system I found, really good - £7 on Amazon. If not, I think you need to clean your throttle body as suggested. Plenty of threads on here to check with.
