well the car is supercharged and the pull tensioner right below the supercharger is bouncing and it moves maybe a half a inch to a inch and makes a good knocking sound when it moves also The exhuast gets red hot by the cat idk if thats normal but i dont think it did that before cuz that last time me and my friend started it it got smoking right by that cat and going in the passanger caparment and the car shuts off i tryed to move it and it will shut shut off when yo u turn it to the left or right its possible it could be the battery cant hold much juice anymore but idk and it will all so turn off if you didnt wait 5 min to give it gas if you gave it gas to early it would shut off

This is a duplicate of the post we saw a couple days back. Please continue with that one as there is good info in that post already.
