My jeep has been running great all day until i went to start it again and it sounded like the battery was dead until I started pushing the throttle then it started but really rough. I let off the throttle then it died. I popped the hood to see if anything was amiss but everything checked out. there is a small leak by the check valve in the break booster but it stopped when i put a hose clamp around it but it didn't fix the problem. I also replaced the check valve but nothing as well. We just had the brake booster replaced too. We can get it to idle if i barely hold the throttle and let go very slowly it will roughly idle at 600 rpm. I included the video of me trying to start it.

No codes?
Ever cleaned your throttle body and IAC?

No but i will clean those. The only code i received was a P0456 the small evap leak but i tightened my gas cap then it went away. Before tearing the throttle body apart today i just messed with the lever while it was off and it started right up so there must be plenty of gunk in there.
