Idle Drops Below 500RPM And Feels Like Its Gonna Stall!! HELP!!
 
Ok, I have been reading posts for the past hour, and never really found an answer.....

So I have a 2008 3.7 4WD Grand Cherokee, and just recently, while I am stopped at a stoplights, my idle briefly goes below 500RPM, and it feels like my Jeep wants to stall, then the idle goes right back up to 700-750. This happens a few times every time I am stopped, with my foot on the brake. I have read several posts saying to #1, clean the IAC valve....Well, from what I understand, my 2008 3.7 doesnt have an IAC...??? #2, I have read to top off the transmission fluid.....Well, again, my 2008 3.7 has a capped transmission dipstick tube!

So has anybody else experienced this low idle/stalling, or does anybody have any suggestions before I end up wasting money, and taking it to the dealership?????

My 07 will drop down to about 450-500 rpms sometimes at a light. The idle gets a bit rougher for sure but it doesn't feel like its going to stall. Also, if it's jumping from 500 to 750 then something is wrong for sure.
Now if I am running the AC or defrost it idles consistent at about 600-650 and is nice and smooth.

Fuel system service or remove the TB and manually clean it.

This is far from a severe issue. I wouldn't even consider it an issue. Just maintenance.

Most would post to use sea foam but I'd rather do the fuel system service from an auto shop.

SEA FOAM :D

It works like a champ to clean all the gunk out of the entire fuel system

So, besides a good bottle of fuel system cleaner (which I hope will cure the problem, but I am doubtful), what other suggestions do you guys have?

That's it. Sea foam or having an auto shop perform a fuel system service will solve your issue.
