ZJ 4.0 problem after running after warm
I have a 95 ZJ that had a failed valve cover gasket. Since replacement the engine has not run correctly after warming up. I tried putting a colder thermostat to see if it would help but the engine still would miss fire at a colder tempatur. I have narrowed it down to being once thermostat is open the problem occurs. I'm lost what to do next I even put a new coolant temp sensor.
