i was driving home from the gym tonight when my car kind of shut down. The engine check light came on and the screen said check injection. The engine was making a deep roaring sound and there was no power. ****ing myself i drove home at about 5mph pulled in the drive turned the engine off and then back on. No engine check light come on and the car sounded fine so i took it for a drive and it was running normal. What the hell could that of been????
