2000 Xj running hot
So today i was at a stop light and I started to notice the jeep start to idle funny. Then all of a sudden there is steam coming from under the hood. I instantly looked at my temp gauge and it was one notch above 210. So i killed the motor, the light turned green and she started back up. I got it to a parking lot and looked under the hood and engine coolent was spewing out of the radiator cap. After it cooled down i inspected the cap and the seals looked normal. I drove it a few miles and it ran funny the whole time, felt like it was misfiring. I saw smoke so i stopped and smoke was coming from motor right by where the fuel injectors are. So i filled both the resvior and radiator back up with water and it still ran a notch above 210 all the way home. I have revved the engine to try and get the thermostat un stuck and i have inspected all hoses and clamps. Note no water was spewing out of cap the last two times I stopped only at first. Also I had a new radiator, water pump and thermostat put in two years ago so none of the cooling systems should be messing up. Im stumped, any ideas?
