2004 Chevy Cavalier completely rebuilt 2.2 ecotec. Dies suddenly
Runs great no codes, going down road the
Trac Off light comes on and then car dies.
Sometimes starts right back other times
will just keep cranking over. New crank
sensor, alternator and Batterry. Will sit and
idle for hours no problem.
Next time it does this check spark plugs for fire and fuel rail for fuel pressure. This will help to narrow down your issue.
Does it go dead when slowing to stop or just random times while driving? If going dead when slowing to stop your egr valve could be sticking open.
