can anyone tell me what the 2nd injector pulse time (ms) should show on my scan tool?

Can I ask what you are looking for and why?

If engine is idling then shouldn't the 2nd injector pulse time be the same as for the others??

I don't know if all scan tools show this, but if you need to see, does your tool provide a graphing function? That would be a better way to know what's going on , if there is a reason to require this info.
