New here, great forum lots of info! I have a 1998 Ram 4x4 SPORT that has a cold idle/ part throttle issue. When I start my truck after a minute or so its starts running real rough, smells like fuel, and I hear a sucking sound(IAC) If I let it warm up it runs fine, if I try to drive cold it will stutter and backfire through the throttle body at part throttle fine at 3/4 throttle or more. 5.2 V8 by the way. Any ideas would really be appreciated. And it is stock no mods with 150,000.
