There are a number of reasons why a car would idle find but sputter when you accelerate. It could need a new spark plugs. You may also have to replace the filters. It might also be an issue with the air flow.
There could be several reasons why a car would sputter and shut off. The car might be out of gas, dead battery, bad starter, alternator problems or other issues. It is best to have it checked out by a licensed mechanic.
A car could sputter in the rain if the car needs new seals. There could also be a spark plug or wire that needs to be replaced.
If it STOPS after 3 miles. Then it sounds like its a fuel problem, and it will also cause your car to shake and sputter. Check fuel filter, fuel pump (listen for a winning sound from gas tank with KOEO). If you have an OBII, check for pending codes...Tom
I should have said that the car seems to sputter at those speeds rather than shake so I don't think it's a tire problem which most people tend to think of.
bad fuel bad spark plugs incorrect timing
FUEL PUMP IS YOUR PROBLEM {why do you think its the fuel pump?}
