LOSS POWER HYUNDAI ELANTRA 1.8 HEATING

Good partners !!! I would like to make a query I have a Hyundai Elantra 96 ​​1.8 which raises the temperature a little of the middle where it is at minimum but as soon as I accelerate the temperature, once the head of the head (or butt) is breathed. I know what to do more and the engine is forced without force at the exit lasts a few seconds to lift. I do not know if the obstructed catalyst that is the only thing that I lack and take out the water pump and this good and the time of the distribution is correct! Thank you for the aid !!! Another little thing I have the light of Check on and indicates Po135 I deleted the code but after a while the light is turned on and does not turn off and feels very hot for the pedals put all the heat out there. Thank you!!!

Hello, when you say that when the accelerate is lowered, do you mean the car in motion or stop?
Have you assured that water with oil is not mixed and/or that the compression of the cylinders does not blow through the water expansion bottle? In case, having replaced the Board of Culate, the surface but the motor block was not planned. All the best

The head or butt is rectified, there is no oil in the water, or water in the oil. The temperature rises little to little while standing on a road on the road as soon as I started and accelerated the temperature begins and even so being without thermostat that is like I walk right now! Thank you
