So pretty much every time I start the Jeep in stalls and will not idle. Once I warm it up it idles just fine. I have cleaned the throttle body, had the idle arm assembly replaced? and also replaced the fuel filter. Still no smooth idle at startup. Thoughts?

 

I feel like I have to ask this every thread. What engine? If it's the 4.0 did you also clean the IAC. And when were the last time plugs were replaced?

 

When you say "idle arm" do you mean throttle position sensor?

 

Plugs were replaced recently. Did not clean the IAC yet
