Replaced Head Gasket, Now Idle Low- Need some help.
Whats up, so long story short, blew radiator hose and then jeep over heated and blew head gasket.
I replaced the head gasket, intake/exhaust gasket, and valve cover gasket.
After that the jeep runs really weird, when its in park its fine, and when im driving its fine but when I am at idle its runs at like 200RPM.
I replaced fuel injectors, distributor cap and rotar, plugs, wires, still nothing.
Currently I got a couple zip ties behind my pedal on the cable to make it run little bit higher idle but is there anything i can do?

I would lean towards a vacuum leak first. The IAC is located right by your tps on the throttle body. It can often get coated with the same gunk covering your tb, so if your tb is really dirty, there is a good chance your IAC is dirty. Most of the time, you can unhook the wire, take the 2 screws out holding it in, pull it out, and clean off the head. I also took q-tips and cleaned out the socket the IAC came from because it was very dirty also. Takes like 30 minutes to do and it can't hurt.

I was having some crazy idle on mine also. I cleaned the IAC with some carb cleaner, and also checked my vac lines. I had both a dirty iac and a vac line that had come off. Idles fine now.
