Typically when a vehicle has a slow starter, it's an indication of a dieing battery. If you're battery is old or "abused" (maybe you listen to the radio a lot with the car off?), it can begin to lose it's voltage, especially under load. If you have a multi-meter, test the voltage of your battery when the car is completely off, when the car is starting, when the car is running and when the car is revved up to mid-low RPM. Reading these voltages can tell you A LOT about the state of your battery and your charging system. if your battery is below 12 V when the car is off the battery is dead. If the battery voltage drops super low during starting it can also indicate a dieing battery. Try it out and let us know the results!
