2008 JKU 155,000 miles recently throwing a multiple cylinder misfire and runs awful above 20mph. Reading up, many suggests I look into the intake gasket. I was losing coolant but not on the ground. Here is what I found under the gasket. Some coolant on the side of the intake as you can see. Hopefully once I get this cleaned up and back together it will run again. Anyone else been through this that can provide any tips from this point forward? It's been pretty straightforward so far.
