If your coils are cracked they all should be replaced. Generic ones are ebay are cheap and I've been running them for a year without issue. I would start there.

The injectors can fail. Most commonly they get stuck open. A sign of this is if your oil smells like gas - just pop open your fill tube and take a whif. If you replace them, swap them all. The ef-1 style Bosch injectors for 03-04 are cheap. Kinda pita to swap though with the air box and sai in place.

You may want to do a vacuum test to make sure it looks good. Smoke tests are not always reliable. Blue62 has written some great posts about doing this type of test.
