Default Need help with car starting...

I need help answering a few questions regarding my car starting.

Sometimes, it seems to start weakly. I'm sure the battery is not drained or anything. What should I be looking out for? What do you think could be causing this? Battery; starter; spark plugs; etc.?

Thank you!

Battery, have it check at an auto store. Most will do it for free.

Does this happen all the time, or once in awhile? As Max Geek mentioned it could be the battery. Another problem might be old or bad spark plug wires, especially moist ones. It could also be a faulty MAP sensor, I think you could probably disconnect it and try starting the car to see if starts normally or starts weakly, if it starts normally then something is wrong with the MAP Sensor...

Let's clarify something first. When you say "weakly", do you mean it cranks the motor over slowly or do you mean it cranks the motor over the same as always but doesn't always fire up in the same amount of time?
A better question will get you a better answer.

Sorry! I'll be more specific. It cranks the motor like a weak battery. It always starts, but sometimes, it has a little hesitation to it.

I'll have the battery checked out. I just wanted to keep an eye out for anything that might be related to bad spark plugs.
