Car sometimes starts on first turn of key, sometimes on the 2nd, third, fourth–seventh, etc–eventually always!! Bought used from CarMax. They can’t fix. Help!!!
Model year?
Odometer mileage?
Maintenance history?
Since this is a used car, it likely did not come with any maintenance records, so it may not be possible to respond to my last point. If the car did not come with maintenance records, then you have to assume that no preventive maintenance has ever been done on the car.
Refer to the Acura Maintenance Schedule (hopefully it is in the glove compartment) and refer to the list of procedures for the major service (30k, 60k, 90k, 120k) closest to the current odometer mileage.
Have everything on that list taken care of, and you should experience better starting, acceleration, and gas mileage. Even if spark plugs are not listed, make sure that the plugs are replaced if you want reliable starting of the car.
