The check engine light has to be on if it's misfiring. What are the code numbers being store?

Then #4 cylinder is where you concentrate on your testing. Test for consistent spark with a spark tester. If spark is good, then check injector pulse with a noid light.

Call around, you may be able to borrow or rent one from a parts house.....
With these symptoms a crank sensor is highly unlikely

No, that's not a likely theory at all. Have you done the compression test as you were asked to?

Yep, that would do it. Don't try to take it apart unless you know what you're doing. If you drop that valve the head will have to come off.

It doesn't sound like you need the light now if your right about the broken valve spring.
