rough idle till warms up
I was driving my jeep down I85 and my temp was runnig normal on my gauge but my jeep started ticking really loud like someone was hitting the valve cover with a hammer. I pulled over and checked my raditor and it exploded then my temp shot to 260. I let it cool down and it idles like sh**. I mean like its running on 3 cyl. After I give it any gas at all it will run fine like it should it just wont idle. I replavced the head gasket, radiator, water pump, thermostat, map, air idle, throttle position and o2 sensor. Im runing 14 codes, random multiple missfires, al injectors, and cyl 1,2,,4,5,6. I took it to a shop and they said they can't do anything bc it was acting fine for them and it idled perfect for me when I got it. Any idea? Please help

Is there any way to test for any of the problems? Im just so annoyed bc my jeep from stop light to stop light will change, it will idle fine, the like crap, then a little rough and so on. Im completely out of ideas, also I changed the plugs and wires and all the stuff your suppose to change when your engine starts running weird

Search it there's lots of threads. Don't want to give you the wrong way. I would unhook the battery and touch the two cables together. Turn on the lights then turn em off... search the correct procedure
