2013 JK jerks while driving and frequently stalls at red lights. Just replaced all coils and plugs and it didn't fix it. Only does it after engine has warmed up. No check engine light. Any ideas?
If it were me, I would get an OBDII scanner with live data diagnostics, plug it in, and drive around while it's recording data in real time. From there you could monitor the engine and see what exactly it's doing that's causing this.
This is what most professional mechanics would do to diagnose it, given there is no check engine light on. The fact that it only does it once it's warmed up is telling.
So my jk periodically will die at stop. I put in park and restart. starts right up. i put it back in drive and it seems to just stay in neutral. I then put back in park. Shut it off and restart and everything is normal. goes in to drive no problem. only seems to do it on hot days and when A/C is...
