i down shifted from 4 to 3 and then 3 to 2 and released the clutch fast and slammed on the gas and the car backfired and cut of and would not star back on pls help me with some ideas.
Thanks guys

 

Bent valves probably.

 

check plugs

 

compression test

 

definately do a compression test. if its good pull your ecu fuse and wait a minute, then put it back in and it should reset your ecu. Then give it a shot. Otherwise youre probably looking at some extensive damage to your internals.

 

Could he have jumped timing when he released the clutch? Check the timing belt after doing a compression test.
