coz you shud of gone to specsavers
I have the same problem and was told it is the fuel temperature sensor.
Bad Valves or fuel pump usually from redlining the care
They start to sputter,stall and stop running.
FUEL PUMP IS YOUR PROBLEM {why do you think its the fuel pump?}
Start with replacing the fuel filter, it may be plugged.
A faulty muffler will not cause this but a clogged catalytic converter will.
There are multiple things that could cause this, your best bet it to take it to a mechanic and let them check it out.
Look for a hole in the PCV valve hose on the backside of the engine.
look to see if your intake manifold is gummed up with residue
A clogged fuel filter or fuel line will likely make your car sputter as if it is going to stall.
Could be many reasons. If the check engine light is illuminated, check for codes first.
A bad fuel pump will cause your vehicle to not start or sputter and then stall. A dirty air filter can have the same symptoms.
