whenever i start my 98 up cold it will run perfect for about a minute... then it will run rough, the rpms dont drop but you can definately tell its not running right by the exhaust, then it goes back to running normal after about thirty seconds or if you give it a little gas and let it drop back to idle

 

check your idle air control and your throttle position sensor

 

i just replaced the idle air, i dont know about the throttle position sensor

 

generally speaking when one goes the other isnt to far behind it i had to do mine like a week apart from each other and so do most other rams ive noticed

 

that makes sense... ill look into it, thanks

 

np is it a 5.2 or 5.9

 

its a 5.9

 

crank position sensor is always a possibility too but highly unlikely

 

ight thnx man
