    Default I Need A Hand

    Ok since i bought this car it has randomly just shut itself down, it doesnt matter whether its hot or cold, dry or wet, fast or slow, long drive or short drive, ive racked my brain for any solution i could think of but the issue im having is that there is no common factor when it dies and mechanics always do some bull fix and say there ya go and most times they jus mess up other things but never the main issue i need fixed if anyone has any ideas about this problem please share it with me thanks =)

    ^ Both the above are likely culprits, and the crank position sensor may also be a possibility (very common on these cars).

    My CPS was flaking out on me for months. Never threw a code (and I've heard the same for countless others with a bad CPS). Also, the coils & ICM don't throw codes.
