PLZ Help, Problem with Irregularity after starting - 2008 KK
I have KK 2008 Limited Edition,
After starting the engine normally, 30 Sec later, Irregularity took place in the engine (during the instability SOMETIMES the check engine indicator light is appear and disappear if I didn't push the accelerator pedal ),
After that the engine get stable and it working normally till you switch off the engine and the check engine indicator still appear.
I Did the following
1) Replaced the fuel pump's filter inside the fuel tank.
2) Opened the Nozzles injectors and check and clean it, its working properly.
3) Replaced the 6 spark plug with new recommended one.
4) Did many computer checks to the car without get a clear error in any sensor, except the O2 sensors (slow response) and this fault is common here in Iraq since we use very bad quality Fuel).
And one of the Guys working in Jeep dealer told me that the problem is with the Fuel Evaporator which located under the back bumper.
I'm really get confused, and I need your help especially who have experience in this issue
