My 2000 jeep cherokee has been having a hard time starting but does start and then it won't stay running unless I'm pushing on the throttle.. but if if I drive down the road then my jeep stays running and seems like there is no issue... even when I come to a stop.. not to sure where to start I know my battery isn't new and could use a replacement. But is that the issue ?

 

My money is on bad battery.

*edit*

Autozone, Advance, and O'Reilly all do free battery testing. Takes all of 5 minutes. I don't know if you can meaningfully test a car battery with just a multimeter.

 

All the stickers are off of my battery so the guy at auto value didn't know the cranking amps ??? To check properly but I did just replace my belt and my tensioner pulley a day or 2 before this has been happening... gonna change out my battery but if my battery was toast wouldn't it not start at all or I'd hear ticking when trying to turn it over

 

For reasons I don't quite understand, a failing battery can sometimes still start the engine just fine, but cause running issues. Think it has something to do with constantly draining output from the generator.

 

what about the idle air control valve?

 

If it were the IAC, I'm guessing that it would have to be stuck closed for there to only be problems during a cold idle. If so, could he test it by removing the IAC and trying to start it up? Should idle ~2500-3000 RPM like that.

 

I changed my battery today..tomorrow I will keep own of that was the problem. But if not I will then look into AIC valve.. thanks for all the help..I appreciate it.. just a question how hard is it change out the block heater.. mine like to spark every now and then when I plug it in. The wires seem fine but it's definitely not easy to see lol

 

Just for S's & G's when was the last time you had the air filter replaced? Have a vacuum gauge?

 

sounds like dirty throttle body or tps sensor

 

So I changed out my battery.. and it hasn't had any issues since. My son left the back light on and I was on night shift so I never noticed it on during the day. I probably could have recharged my battery and might have stopped acting up but she was due for a new battery sooner or later. Damn kids
Thx for everyone's input I appreciate the help
