I have a 2006 jeep wrangler2.4 liter with a engine light on and a po344code. already had cam sensor and crank sensor replaced. new spark plugs and wires.new wiring harness,timing checked and not ran for 8 hours and the outside temperture is timing belt replaced,new coil pack,new IAT sensor.When I first start my jeep after it has below 48 degrees, it will rough idle when r.p.m.'s are over 2000 and the engine light comes on. I then turn engine off and resart my jeep and then it runs fine and the engine light eventually goes out again. Can you please tell me what is wrong?
