Was driving home from work tonight was doing about 20mph and my car has died. All of a suddern it lost all power, the revs dropped right down and cut out. When I started it again it cut out straight away. eventually when I got it going the revs were hunting, dropping really low to around 300rpm.
I tried to put my foot down when I got it moving but at 1 point I had my foot flat on the floor and it went nowhere just spluttered with a bit of a backfire. I thought it may be some crap petrol as I didnt go to my usual garage when I filled up so I filled the tank up again and put some injector treatment in incase I had some grit in my petrol maybe a sticky injector but it aint working. Its still really lumpy and I cant go anywhere in it cos it just keeps dying.
Whats wrong, it was perfect thisd morning.
Please help
