Discussion:
#3 cylinder missfire

Update

Finally found the problem with missfire on #3 when hot. After changing all ignition components I swapped injector rails with another unit and problem solved. I did not want to buy a complete set of injectors just to try it. One of the other units with the same 2400 GM engine broke a timing belt so I swapped injects fromm that unit.

If you changed all that and still have problem did you every think of taking a compression test to see if you have good compression to fire a spark plug.
