hi guys, I recently bought a ba xr6 turbo with a btr in it. I'm having a problem where basically the engine stalls and normally after it stalled it will not crank over. Sometimes it will crank straight away but most of the times it will take a minute or two until I can start the engine again. this issue can happen at any condition at all. Already installed new coils, plugs and a new crank angle sensor. Apart from the car drives fine. Any ideas of what it could be?
