Re: taurus misfiring like crazy Sign In

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.

Re: taurus misfiring like crazy Sign In

Call around, you may be able to borrow or rent one from a parts house.....

With these symptoms a crank sensor is highly unlikely

Re: taurus misfiring like crazy Sign In

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

Re: taurus misfiring like crazy Sign In

I took off the valve cover and found that one of the springs were broke that must be it right ?

Re: taurus misfiring like crazy Sign In

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.

Re: taurus misfiring like crazy Sign In

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