mine was doing that and i replaced the throttle position sensor. helped me.. if you have a check engine light on go to a mechanic and get them to run a diagonistic that should tell you exactly what it is

I had this same issue on my 97 tj. I replaced the Iac and the tps I replaced the vacuum line (from this fuel rail to the throttle body) I wa at a loss...just for fun I sprayed a little throttle body between the intake manifold and the block. It made the engine stumble and sputter...turns out the bolts holding the intake on were loose...it works fine now so try it out

Thanks for the help, though note the post you responded to was nearly three years old. A big welcome to JF, good to have you here!

I have replaced my IAC, cleaned the TB 3x and still nothing. I did notice that upon spraying Carb cleaner at the line from the PCV elbow to the Intake Manifold there was a stutter.

Could you show me the bolts you are referring to? I am not sure if I need to replace the vacuum line or what. I am one weekend away from just taking this to the mechanic and washing my hands of this issue. Should I look into replacing the TPS as well? because a new IAC didn't do a darn thing but make it worse.
