The car started making a noise, took it to auto zone & they said it was the belt tightener. The car was having a hard time driving up hills on the way home after getting the part. It actually stalled out at a red light, making it very hard to break. After getting it home & replacing the part the noise was still there. We were going to go back to auto zone to see why & while driving on the way there a valve came shooting through the engine. It was quite alarming sounded like a shot gun went off. We picked up the broken valve, parts of it looked melted, & towed the car home making sure no cars hit us we pushed the car off the rd. Thank god we were not on a hwy with my 5 month old & 11yr old.
