I have a 2004 Kia Sorento and it was running fine with no issues than the other night when driving home from hockey it started making a sputter/scraping noise when i would accelerate at 50km/h and then when i came to a stop it would stall this only happens when its running at normal operating temperature when the vehicle is completely cooled off it doesnt make any noises or any problems until it hits normal temperature or halfway on the gauge what is wrong with my vehicle my life depends on this vehicle
