does the iac have any effect after throttle is pushed, 96 5.9 ,stumbles and dies sometimes at an idle and sometimes stumbles and jerks while driving at a steady speed, other than yjat,runs great, any ideas, I am new to the dodges, cleaned aic and installed new o2 sensors, Lee

 

Are you talking about the Idle Air Control when you said aic?

 

Yes that could be the problem. When mine went I would just be drving and when I let my foot off the gas it'd die. If you've already replaced it clean the whole TB out, if you haven't go pick up a new one and still clean the TB out. Theres tons of crap in there.

 

the iac has nothing to do with how it runs while the throttle plate is open (foot mashing gas). it only performs any function when the throttle plate is closed and you need air to pass around the closed plates.
