Well I see a couple of threads but again not really my issue.

1 I replaced the battery and some times my Jeep grunts to start.

2 When in a cold start the engine runs only at idle never a tick up like the wifes car. I had this happen once on a Honda and it actually affected the way it ran. this doesn't affect it but it takes a while longer to warm up.

Thanks Guys

Merry Christmas

 

mine i sometimtes have 2 put mine n neutral and it starts right up.

 

My starter does the same thing every time, regardless of temperature, the only thing that changes is the rate at which it does this: "dunna dunna dunna vrrnnnnnn" and then it settles itself out. Engines cranking over slower in colder weather is perfectly normal. Just give them a chance to warm up before you drive.

 

mine doesn't start till like 5 seconds, but i think it's my battery.

 

There's a simple way to test that that doesn't require a new battery. Get a jump start from another vehicle before you start it, and try it then.

 

Yeah, my general rule of thumb is that if its below 35-40 degrees out, let it run for about five minutes before you drive it. And part of the sluggish start is the additives in our gas now, they do that at a lower temperature. And if you start it in the cold, and don't run it for more than 5 minutes and shut it off, don't expect to get it started back up right away. LOL.

 

Five minutes... I really will be nicer to my XJ.
