Default Injector question.

On a TPI engine do the injectors all fire at the same time or do they fire at timed intervals? I sure they fire at different times but not 100% sure

Thanks

They are batch fire, so all 4 on each side fire at exactly the same time.

The previous owner of my '90 had new fuel injectors installed on the car. The shop receipts don't indicate manufacturer or the size (in lbs.)
The are like a puple color. What do the different values of the the injectors mean ie. 24 lbs, 28 lbs etc. and where are they best applied?

Since you are new it is not nice to hijack a thread.It would be better to start your own and ask what are the differences between injector sizes and you will get more answers that way too.
