GTA4 Dead Engine Glitch PS3

I read about this on the GTA wiki and thought I'd give it a try - it actually works! At least on the PS3, don't know about the Xbox360 version. About the glitch: Whenever your car's engine doesn't start anymore, simply take out your cellphone and call someone. While the phone is dialing, just press the R2 or L2 button to accelerate and the engine should start. Have fun!
