I have a 2005 dodge ram 4.7L and I’m having a problem, starting the truck when motor is cool or hot it will idle up and down up and down up and down but never putting out a check engine code. The problem started after I got another truck to drive back and forth to work and I let it sit for about four weeks just driving it on the weekend, dose any one have any suggestions?

same thread

There are lots of threads on idle issues and can range from TB needs to be cleaned, bad fuel (not good to let ethanol blended fuels sit as it absorbs moisture and separates), EGR maybe clogged, vacuum leaks

 

does it feel like it drives rough as well? or is it only idle

 

yeah it fills like its lost some power

 

does it stumble or sputter at any certain speeds?

 

and when i push the throttle and hold it in one it fills like it steps up in power instead of a smooth exceleration

 

yeah every now and then it will sputter like its gonna choke out and then it picks up and takes off

 

i would look into your egr, or your tps

 

i will give both a shot thanks for your help

 

i would diagnose them first, im not telling you to replace them, unless you want to go that route. but diagnosing would help you save some green.
