hey, my 2002 dodge ram 1500 4 dr truck is having this issue ... when i bought it, it was fine, everything seemed great... about a week later everytime i start it, it doesn't idle consistently. the rpm fluctuates from .5 to 1.5 constantly. i've let it sit for up to 10 mins to see if it gets better after a while, but it doesn't. i try to hit the gas a lil to see if that makes any difference, and it doesn't. i'm not mechanically minded at all, so any advice would be helpful! maybe theres an easy trick someone knows ?

 

Welcome to DF.

First, before anything else, please read this:

I will move you to the 3rd Gen Ram section (2002-2008 Rams).

Which engine do you have?

 

first thought is what Jasonw asked above. second thought i to pick up some carb cleaner spray and use it to try to detect any vacuum leak from any hose or nipple or throttle body seal as a vac leak would give idling issues.

im assuming you have done proper maintenance on it like plugs and wires and rotor/cap (5.9) ect.

 

i have the same exact rpoblem with my 02 ram with the 5.9L. idles the same as described. would love to hear a fix. havent really gotten a chance to check it out. could b a possibe vacuum leak. proper maintenance has been done ( plugs wires cap rotor and everything else).
