Exclamation Starting Issues

Sometimes when I start my Jeep it will keep turning over, so I'd let off and sometimes it would catch and slowly the rpm's will go up to idle speed. Other times it will crank and crank but never catch so I have to keep the throttle wide open to get it to start, but then I have to feather the throttle for a while, then after a while it will idle on it's own. Any solutions/thoughts?

Does it do it all the time or just when it's cold outside and the Jeep is not warm?

It depends it can be -20 below and start fine or it can be 40 degrees and not start, and vise-versa.

Oh I see my truck a 97 f-150 starts real hard and you have to hold the rpms up at 1500 or so for a few minutes until it will idle on it's own when it's around 10 degrees out

Maybe it's the cold, but the starting varies day to day and the temperature.

Could be the battery cables, I know I need to replace them, never would think that would be a problem. It's not really a big deal, I just get made fun of at school, they think my Jeep is a POS, so I just wanna fix it. But again, it's not that big of deal.

Sounds very similar to what my F-150 was doing when the idle air control valve was sticking. You should be able to take it off and clean it to see if it helps. Never done it on a Jeep, but it was very simple on the Ford.

I'm no mechanic and never claimed to be one....just tossing out an idea.

OK, I've had some new issues arrive but they went away, and I have a feeling they will be back. Yesterday when I left for lunch my check engine light came back on, and the idle RPMs were at 2000, also when driving once the engine reaches 2000 RPMs it sounded like a marble rattling around a tin can inside the engine. After school the check engine light went off and it idled fine, after driving awhile, I came to a stop at a stop signand it was idling at low RPMs lower than 500 RPMs. Could this still be the idle air control valve?
