i dont know but i got the same problem i've already changed the spark plugs,the wires,the Ignition Coil,the Fuel Injectors,the pvc and egr valve and the car heats up but i dont get a reading on my Temperature gauge and the fan doesn't cut on. i don't really what else i can do the mechanics keep telling me they don't know whats wrong with it but if i try going full throttle i get a very heavy bog the car feels almost like im slaming on the brakes the the car revs super high to the point that i have to get off the throttle beacuse i feel like i'm going to blow the engine
