How's your fuel pressure, and is your return line obstructed anywhere that you're aware of?

All of them, or just certain ones?

Just replace them. They should only open with electrical impulse.

If they are 19's, grab another set

Have you checked the 10-pin connectors behind the intake yet? These are the injector wiring harness connections. After 15-20 years or so, they start to lose their connection strenght and start doing all funky things with the fuel injectors.

If you have the jumper harness for these, remove it, then clean off all the gunky dielectic goo, spread the pins open with a small pin and reconnect
