weird misfiring

[Gc01]

Hi, I've been having some car troubles today so I turned on my car and it was fine then I drove it forward and it started misfiring and it was idling badly and I had to keep reving it to stop it from cutting out. It was running fine last week I havent done any changes. Also the power steering light comes on. Now the car has electric power steering so there is no pump to replace so I don't know what to do.

Maybe have Battery and alternator test. Then a diagnostic one.

Check the Battery voltage across the terminals (with ignition off)

Anything less than 12.4V suggests Battery is dead or alternator faulty.

 

If the Battery is  more than 5-6 years old, odds are it's the battery - especially if car has not been used much. Try putting the battery on a charger. (borrow if possible)

 

Garages selling batteries will usually do a check.

 

But  as above , it could be the alternator
